The British film industry is a very diverse thing. Almost no British film is made without co-production of some sort."British technicians, actors, writers, directors, and musicians are right at the core of film-making and you always see that at the Oscars."The winners of the golden statuettes will be announced at the 86th Academy Awards on Sunday, 2 March at the Dolby Theatre at the Hollywood & Highland Center in Los Angeles.
