No! This is a Brian May from Australia. The only soundtracks our Brian has done are the ones Queen has done, and music for Shakespeare's play Macbeth done by the Red and Gold Theatre Company in London, but this music is not commercially available. Two specific ones that come up frequently are the soundtrack for "Road Warriors" and for "Nightmare on Elm Street (Freddie's Dead: The Final Nightmare)"--these are absolutely *not* our Brian! (Update, the Australian Brian May passed away several months ago.)
Not quite film scores, but "our" Brian has done music for the UK Spiderman radio series. This music was performed and released under the pseudonym "MC Spy-D and Friends". He also did the musical score for Macbeth for the Red and Gold Theater Company in London, but this music is not commercially available. Brian also did music for the "Rise of the Robots" computer game. Because of Brian's record label, however, not as much of Brian's music was used as was originally intended.
