Yen was born in Guangzhou, China. His mother, Bow-sim Mark, is a Fu Style Wudangquan (internal martial arts) and Tai Chi grandmaster, while his father, Klyster Yen (Zhen Yun Long ), is a newspaper editor. When he was two years old, his family moved to Hong Kong and then to Boston when he was 11. His younger sister, Chris Yen, is also a martial artist and actress, and appeared in the 2007 film Adventures of Johnny Tao: Rock Around the Dragon.
Donnie Yen was considered as one of the premiere action choreographers in the world, having been invited by Hollywood to choreograph blockbusters such as Blade II, Highlander: Endgame, and Shanghai Knights. In Asia, he is the action choreographer for most of his movies and has won multiple awards for his action choreography. Yen's most famous works include films such as Flash Point and SPL: Sha Po Lang. He has mentioned that the main differences in filmmaking in Asia and Hollywood are with regards to freedom and control. In Asia, the action choreographer takes over the scene during the fight scene. This means that for action scenes filmed in Asia, the choreographer becomes the director and is in full control over camera placements, camera angles, and the relationship between the drama and the action; therefore the main director is not needed at all. While in Hollywood, on the other hand, Yen explains that the action choreographer simply choreographs the actions with the director, who still maintains full control of such settings and camera angles. Yen's work as a choreographer won him "Best Action Choreography" awards at the 27th Hong Kong Film Awards and the 2008 and 2011 Golden Horse Film Awards. Yen was the fight choreographer for the 2010 film Legend of the Fist: The Return of Chen Zhen. For this film, Yen mentioned that he included Jeet Kune Do elements as a tribute to Bruce Lee, who played Chen Zhen in the 1972 film Fist of Fury. Furthermore, he incorporated many MMA elements in the film, coupled with the utilisation of Wing Chun. Yen also stated that the concept behind Bruce Lee's Jeet Kune Do is similar to that of MMA, hence the incorporation of many forms of martial arts was a necessity in the film. He won the Hong Kong Film Award for Best Action Choreography 4 times, being one of the most frequent winners of this coveted award. He has won awards for his choreography in films such as The Twins Effect, SPL: Sha Po Lang, Flash Point, and Kung Fu Jungle. Although uncredited, Donnie Yen was also action co-choreographer for Hong Kong Film Award winners such as Ip Man, Ip Man 2, and Bodyguards and Assassins.

Are there any other noteworthy performances?

Def Leppard are an English rock band formed in 1977 in Sheffield as part of the new wave of British heavy metal movement. Since 1992, the band has consisted of Joe Elliott (lead vocals), Rick Savage (bass, backing vocals), Rick Allen (drums, backing vocals), Phil Collen (lead and rhythm guitar, backing vocals), and Vivian Campbell (rhythm and lead guitar, backing vocals). This is the band's longest lasting line-up. The band's strongest commercial success came between the early 1980s and the early 1990s.
Rick Savage, Tony Kenning, and Pete Willis, all students at Tapton School in Sheffield, South Yorkshire, formed a band called Atomic Mass in 1977. The band originally consisted of Willis on guitar, Savage on bass (after originally playing guitar), and Kenning on drums. Only 18 at the time, Joe Elliott tried out for the band as a guitarist following a chance meeting with Willis after missing a bus, in November 1977. During his audition it was decided that he was better suited to be the lead singer. Their first ever gig was in the dining hall in A Block in Westfield School in Mosborough, Sheffield. The band adopted a name proposed by Elliott, "Deaf Leopard", which was originally a band name he thought up while writing reviews for imaginary rock bands in his English class (and in at least partial reference to Led Zeppelin). At Kenning's suggestion, the spelling was slightly modified in order to make the name seem less like that of a punk band. In January 1978, Steve Clark joined the band. According to Elliott, he successfully auditioned for the band by playing Lynyrd Skynyrd's "Free Bird" in its entirety. In November, just prior to recording sessions for what would be a three-song release known as The Def Leppard E.P., Kenning abruptly left the band; he would later form the band Cairo. He was replaced for those sessions by Frank Noon. By the end of the month, Rick Allen, then only 15 years old, had joined the band as its full-time drummer. Sales of the EP soared after the track "Getcha Rocks Off" was given extensive airtime by renowned BBC Radio 1 DJ John Peel, considered at the time to be a champion of punk rock and new wave music. Throughout 1979, the band developed a loyal following among British hard rock and heavy metal fans and were considered among the leaders of the new wave of British heavy metal movement. Their growing popularity led to a record deal with the major label Phonogram/Vertigo (Mercury Records in the US). Def Leppard's original management, MSB, a local duo consisting of Pete Martin and Frank Stuart-Brown, were fired after Martin and Joe Elliott got into a fistfight over an incident on the road. The band approached Peter Mensch of Leber-Krebs management, who had booked them on a tour of the UK supporting AC/DC. Mensch, who admitted that he had had his eye on the band, became their manager.

Did this turn into Def Leppard?
