Ewan McGregor‘s back in Scotland celebrating Trainspotting‘s 30th birthday.

The Hollywood star, famed for roles in the Star Wars prequel trilogy, Moulin Rouge!, Black Hawk Down, Down With Love, and who is currently in theaters with The End of Oak Street, spoke at an Edinburgh International Film Festival session on Friday afternoon, shortly before a party celebrating the anniversary of Danny Boyle’s 1996 film, which launched McGregor to stardom. The live event is set to host McGregor and his Trainspotting castmate Ewan Bremner, as well as producer Andrew Macdonald, screenwriter John Hodge and author Irvine Welsh for an in-depth conversation about the cult film, centered on drug addiction and urban poverty.

The conversation was hosted by Berlinale director Tricia Tuttle, who kicked off the proceedings by asking McGregor about his upbringing in Crieff and whether he feels patriotic as a Scotsman in showbiz. Over the course of 90 minutes, McGregor entertained the tightly packed crowd at Edinburgh’s Central Hall with anecdotes about working with Baz Luhrmann, making a film with his 30-year-old daughter and getting naked (which had McGregor re-enacting the moment he slipped over, nude, in front of “300 old ladies” during a stage performance of What the Butler Saw).
