# Arrow season 3

The third season of the American television series Arrow premiered on The CW on October 8, 2014, and concluded on May 13, 2015, with a total of 23 episodes. The series is based on the DC Comics character Green Arrow, a costumed crime-fighter created by Mort Weisinger and George Papp, and is set in the Arrowverse, sharing continuity with other Arrowverse television series. The showrunners for this season were Greg Berlanti, Marc Guggenheim and Andrew Kreisberg. Stephen Amell stars as Oliver Queen, with principal cast members Katie Cassidy as Laurel Lance, David Ramsey as John Diggle, Willa Holland as Thea Queen, Emily Bett Rickards as Felicity Smoak, Colton Haynes as Roy Harper, John Barrowman as Malcolm Merlyn and Paul Blackthorne as Quentin Lance also returning from previous seasons.
The series follows billionaire playboy Oliver Queen (Stephen Amell), who claimed to have spent five years shipwrecked on Lian Yu, a mysterious island in the North China Sea, before returning home to Starling City (later renamed "Star City") to fight crime and corruption as a secret vigilante whose weapon of choice is a bow and arrow. In the third season, Oliver's company Queen Consolidated is sold to businessman, scientist, and aspiring hero Ray Palmer (Brandon Routh) who changes the company's name to Palmer Technologies and hires Felicity as vice president. After Sara is found murdered, Oliver becomes embroiled in a conflict with Ra's al Ghul (Matt Nable). He struggles to reconnect with his half-sister Thea who knows Malcolm is her father. Laurel sets out to follow Sara as the Black Canary. Meanwhile, John becomes a father and struggles as a family man. The season features flashbacks to Oliver's third year since he was presumed dead, where after escaping Lian Yu, he is forced to work for A.R.G.U.S. leader Amanda Waller (Cynthia Addai-Robinson) in Hong Kong. Oliver and Tatsu Yamashiro (Rila Fukushima) work to stop corrupt general Matthew Shrieve (Marc Singer) from unleashing a pathogen which Ra's al Ghul acquires in the present.
The series was renewed for its third season on February 12, 2014, and began filming in Vancouver, British Columbia, Canada in that July. Despite a strong critical start for the season premiere, the season received more negative reviews than the previous seasons, and averaged 3.52 million viewers each week.

The season was released on DVD and Blu-ray on September 22, 2015. The series was renewed for a fourth season in January 2015.

## Production
### Development

Arrow was renewed for a third season by The CW on February 12, 2014.

### Writing

Talking ahead of San Diego Comic Con, executive producer Marc Guggenheim stated that the theme of the season would be 'identity'. He and fellow EP Andrew Kreisberg confirmed that the series would continue six months on from the end of the previous season. Producers confirmed that the flashback sequences would continue this season, but be focused on Oliver's time in Hong Kong, and also examine the beginnings of his relationship with Amanda Waller.
Regarding character arcs, Guggenheim confirmed that both the characters of Thea Queen and Laurel Lance would be developed further over the season saying "Laurel and Thea are the two characters we haven't done as much with in the past, and they have the strongest storylines that we've ever given them." In particular, Thea's relationship with her father Malcolm Merlyn would be further explored, including a flashback to their encounter in the season two finale. Regarding Laurel, Kreisberg stated that "We're going to see Laurel take a few big steps toward her comic book self this season." Following previous revelations that the first episode would feature a date between Oliver and Felicity Smoak, Kreisberg stated that "The way the show has shaken out and the experiences the two have had, it feels like it's time to explore that." He also confirmed that Brandon Routh's Ray Palmer would be "invading Oliver's life in every aspect", as well as injecting more humor into the season.
It was also disclosed at San Diego that the season would feature an episode exploring the origins of the character Felicity Smoak, to be entitled "Oracle", which would focus on her time at M.I.T. It was confirmed by Marc Guggengheim in August that the episode name had been changed to "The Secret Origin of Felicity Smoak" and that the episode would also introduce Felicity's mother, Donna Smoak.
Kreisberg also confirmed that Colin Donnell would make an appearance as Tommy Merlyn in the second episode of the season, during a flashback sequence.
Guggenheim originally discussed with the other writers about bringing Jessica De Gouw back as Helena Bertinelli / Huntress. However, despite the crew loving to work with De Gouw and De Gouw's interest in returning, the season ultimately proved to be too short for a Huntress episode given that they ran out of stories to include in a 23-episode season, like that of Felicity Smoak's parents, not wishing to waste the character for an episode that couldn't do her "justice". As a compensation, it was decided to bring the Huntress back in the Arrow: Season 2.5 comic book series while planning to bring De Gouw back for the next season upon learning of the show's renewal.
The preview of the third season trailer revealed the season 'big bad' to be Ra's al Ghul. Talking about potential story arcs, Kreisberg noted the possibility of Oliver working with Malcolm Merlyn against Ra's – "We've established firmly that Ra's al Ghul hates Merlyn and Oliver doesn't like Merlyn. It's going to be series of who hates who more. The enemy of my enemy is my friend."

### Casting

In July 2014, the series cast several season regulars, including Brandon Routh as Ray Palmer along with J. R. Ramirez was Ted Grant / Wildcat, Karl Yune as Maseo Yamashiro and Rila Fukushima as Tatsu Yamashiro. Devon Aoki was originally cast to play the latter, but scheduling conflicts led Aoki to be recast as Tatsu with Fukushima. Vinnie Jones was also cast as Danny Brickwell, in a guest role. The following month, it was announced that Charlotte Ross would be joining the series as Felicity's mother, Donna Smoak. Later the same month, Nolan Gerard Funk was cast as Felicity's former boyfriend Cooper Seldon. In September, Matt Nable was cast in the role of the season's antagonist, Ra's al Ghul. Film actor Liam Neeson, who played the character in the Christopher Nolan Batman films Batman Begins and The Dark Knight Rises, originally expressed an interest in reprising the role for the show, but couldn't take up offer when the showrunners approached him due to scheduling conflicts. Amy Gumenick was cast in a guest role as Carrie Cutter in the same month. Caity Lotz was confirmed to return as Sara Lance for at least three episodes at the start of the season.

### Filming

The DVD and Blu-ray box sets contain additional features, including making-of featurettes, deleted scenes, gag reel, and highlights from the Paley Fest.

## Reception
### Critical response

Despite a strong critical start for the third-season premiere, the season received more negative reviews than the previous seasons.
Writing for Entertainment Weekly, Chancellor Agard noted that season had been an uneven one where the "highs have been rather high and the lows have been almost insufferable" and highlighted that the season' biggest problem seemed to lie in the characterisation and motivation of the season's big bad, Ra's al Ghul. He did however praise the development of the character Laurel Lance as well as the development of Oliver's relationship with John Diggle.
Katie Kulzick, of The A.V. Club noted that the season had a habit of "making bold moves and all too frequently backing away from, rather than embracing, the ramifications of these series-altering decisions." Despite the season's "significant problems", she felt groundwork had been laid for interesting potential storylines, in particular the development of Thea Queen becoming a member of the team omni man as Speedy, for Felicity Smoak with Palmer Technologies and for Oliver to develop a fresh perspective.
The season finale was described as "dull", "lacking scope", and "underwhelming" by IGN's Jesse Schedeen in light of the "high standard" the show had previously established for its finales. He cemented the mixed reception of the third season as being "haphazardly paced" and "struggling to develop a clear sense of direction".
The third season holds a score of 90% on Rotten Tomatoes based on 9 reviews, with an average rating of 8.37/10. The site's consensus concluding: "Arrow stays on target with new characters and a steady supply of exciting action."
