Mick Jagger may be wavering, but Tim Roth paid an unexpected visit to the Edinburgh International Film Festival last night (August 15) to introduce the event's surprise film - Planet Of The Apes.

The festival is now hoping that Jagger, who was to have been the star guest this weekend, changes his mind after publicists said that he is unlikely to attend. The Rolling Stones front-man was to hit the Scottish capital for the international premiere of Enigma, the first film from his production outfit Jagged Films. But the pressure of finishing off a solo album means no one will know for sure if he is coming until he arrives.

Kate Winslet may, however, turn up for Enigma, which screens on Saturday. Scottish actor Dougray Scott is amongst those confirmed for the Intermedia film. Sean Penn is scheduled to arrive towards the end of the festival for The Pledge, along with Robin Wright Penn.

Emma Thompson is to attend for closing film, Wit, and may give a public interview with festival artistic director Lizzie Francke. Ghost World, screening on Friday, is expected to be supported by director Terry Zwigoff and actors Steve Buscemi and Thora Birch.

Kooky French hit Amelie, which opened the festival on Sunday (August 12), has so far proved the most popular film in the audience poll. UK title Gabriel And Me is next, followed by Thai western Tears Of The Black Tiger. It also emerged that Norwegian film Cool And Crazy, which opened the documentary section, was picked up for the UK in the run-up to the festival by indie distributor Artificial Eye.

Amelie director Jean-Pierre Jeunet was amongst those attending, giving a public interview. Other guests so far included Glasgow-born comedian-turned-actor Billy Connolly, in town for Gabriel And Me, apparently with his beard died green in honour of football club Celtic.

Jagger fans, however, can at least rely on the Fringe arts festival which runs alongside the film event. The rock 'n' roll legend appears alongside an Edinburgh health-and-safety inspector and a camp cocaine vendor amongst the characters in the well-received comedy sketch show, Crouching Ferret, Hidden Beaver.
