How did Walter Salles, director of The Motorcyle Diaries, find shooting a leper colony scene in the depths of the Amazon rainforest? What concessions was theatre turned film director Richard Eyre prepared to make for modern audiences in his new Restoration Comedy Stage Beauty? When does Zbigniew Preisner, composer for Krzysztof Kieslowski among others, decide silence is the best soundtrack? Does Ken Loach think subtitles for Scottish films are insulting?
Edinburgh is not a big starry event on the level of, say, Cannes, but still attracts a fair smattering of famous faces. Obvious places for sleb-spotting are the opening and closing galas.
The festival starts strongly with Walter Salles' The Motorcycle Diaries, a much feted adaptation of revolutionary pin-up Che Guevara's autobiographal journal about his travels as a young man through South America.
At 23, it would be fair to say that Natalie Portman is a veteran. The Israeli-born actress has almost 16 films to her credit already, her best-known role of which is probably Senator Padme Amidala in George Lucas' Star Wars prequel trilogy.
Ron Perlman could not have been more surprised that Hellboy, a comic-strip superhero who looks like a devil but does battle with the forces of evil, was written with him in mind. So of course, how can the tall character actor possibly say no to writer-director Guillermo Del Toro?

Colin Farrell was in top form during his brief meeting with local journalists, here in Los Angeles to promote the small, indie film, A Home at the End of the World.

Nothing has changed for the 28-year-old who, when we met during the Daredevil junket, mentioned his mother's concerns over his love of profanity, smoking and various other extra curricular activities.
Los Angeles At the conclusion of the new Will Smith movie I, Robot, a fellow audience member was heard to remark: 'That Will Smith is such a personable young actor'. The next day, the casually attired movie star says that he is more than comfortable with that particular persona.
The technology is getting better, the prices continue to come down and some post-production houses are becoming masters of the video-to-film process, but shooting a film on video and blowing it up to 35mm film can still seem something of a dark art.
Part of the reason for this is that cameras and technology are changing so quickly. What seemed the best balance between cost and creative values a year or two ago may no longer hold true. But also, each project is unique and may require a different solution and aesthetic.
Rising British star Clive Owen wants to make it clear that he is not in talks to be the next James Bond.
