Apparently it has been seen by more than 20 million people.
Yet, it could well be one of the Harry Potter films, possible The Philosopher's Stone. Or maybe, Four Weddings And A Funeral- another hugely popular British film.

A fellow Gemini, too!
Good luck with the puzzle + may you be mightily blessed in 2009 geminijune :-)
