He is perhaps best known for producing several feature documentaries that premiered at the Sundance Film Festival, including Valentine Road (2013), This Film Is Not Yet Rated (2006), and Twist Of Faith (2005), and for directing and showrunning television projects including Chelsea Does (2016) and (2016). The 2014–15 season was Arsenal's 23rd season in the Premier League and 95th consecutive season in the top flight of English football.  This season Arsenal participated in the Premier League, FA Cup, League Cup, Community Shield and the UEFA Champions League.  An inconsistent start to the league season ended any realistic hopes for the Premier League title as Arsenal only won two out of their first eight games.  Inconsistency plagued Arsenal throughout the first half of the campaign, not helped by numerous injuries to important players.  At one stage, Arsenal were as low as eighth heading into early December.  This would later haunt them as they mounted a superb recovery during the second half of the season where they won eight league games in a row, becoming the in-form side of the division.  Ultimately, however, the gap between themselves and leaders Chelsea was too much, the points dropped during the inconsistent first half of the season proving too much to recover.  Old habits were hard to eradicate in Europe as yet again, Arsenal were their own worst enemies.  Despite being widely expected to reach the quarter-finals, having been given a favourable draw in the Round of 16 against AS Monaco, Arsenal self-destructed at home, where panic led to Monaco winning the first leg 1–3, a scoreline which ultimately proved fatal over the course of the tie.  Arsenal, with their 0–2 away win proving useless, bowed out yet again in the round of sixteen for the fifth consecutive year.  However, Arsenal reclaimed the FA Cup, thus becoming the most successful club in the history of the competition with twelve wins, comfortably beating Aston Villa 4–0 in the final.  Arsenal finished the league season in third, thereby qualifying directly to Champions league group stage and avoiding the Champions League qualifier, something Arsène Wenger was keen to avoid as he felt it had a negative impact on competing for the Premier League title, which was the primary target set by the players, manager and coaching staff, going into the next season. The Incredible Moses Leroy, the alter ego of ex-substitute teacher Ron Fountenberry, is an indie artist.  The name is a juxtaposition of "The Incredible", a reference to a comic book, and his great-grandfather (a civil rights activist) Moses Leroy.  His song "Fuzzy" was featured in This Film is Not Yet Rated, and on an episode of the American television sitcom "Scrubs".  "The 4a" was used in the film "P.S".  Along with members of "El Ten Eleven", Fountenberry has gone on to form the band Softlightes.   Club Test 01 is Bloom 06's first EP, released on November 28, 2008 in Italy.

Following is a re-imagined version of the group's previous hit, Blue (Da Ba Dee), then an English version and remix of "Un'altra Come Te".  Ending the EP is a remix of "Welcome to the Zoo", yet to be released for preview. David Ansen was the Artistic Director of the Los Angeles Film Festival from 2010 until 2014.

They are currently competing in the Northern Premier League Premier Division.  The club was founded in 1874, playing challenge matches organised on an ad hoc basis until the 1877 season, when they entered the Welsh Cup for the first time.  The club entered two other competitions (The Cheshire Senior Cup in 1879 and the FA Cup in 1882) before finally playing league football in The Combination in 1890, for which they were founding members.  They became founding members of the Football League Second Division in 1892, where the club remained for two seasons, and are the only two seasons in the club's history where they have played professionally and in the Football League.  In the 1894 season, they returned to amateur, regional football when they rejoined the Combination.  Two season in the Cheshire League followed until the turn of the century, when Northwich joined the Manchester League in 1900, when they finished as runners-up.  Two seasons later, for the first time, they won a league trophy as winners of the Manchester League in 1902.  They departed the Manchester League in 1912 when they joined the second division of the Lancashire Combination, finishing 4th in the first season, which ensured their promotion to the first division.  In 1919, they became founder members of the Cheshire County League, where they remained until the 1968 season, winning the league just once in the 1956–57 season.  Following their departure from the Cheshire County League, they became founder members of the Northern Premier League.  In 1979, they founded yet another league, the Alliance Premier League (now known as the Football Conference, where they remained until their relegation in the 2004–05 season.  During their time in the Conference, they won the FA Trophy in the 1983–84 season, and finished runners-up twice in 1982 and 1995.  They returned to the Conference National at their first attempt when they won the Conference North in the 2005–06 season.  However, ongoing financial issues in the latter part of the 2000s saw them relegated twice in two season; in 2009 they were relegated back to the Conference North and then again the following season to the Northern Premier League Premier Division, where they are competing for the current season.
