Homecoming unveiling for star pair Sam Riley and Alexandra Maria Lara

If you're a cinephile who was unaware of Ben Wheatley's upcoming film Bulk, starring Leeds actor Sam Riley, don't worry, you're not out of the loop - hardly anyone knew about it outside of the production. Now it is almost time for its world premiere at the Edinburgh International Film Festival, after which there will be a special screening in Bradford.

"Things get talked about too early these days," Ben said. "It wasn't secret; I just didn't want to talk about it until it was done and then it just makes it more special for the first screening, for that premiere it's like that is a real event, rather than knowing loads of stuff about the movie," he says.

Promotional material has promised a "genre-blurring journey through alternate realities, packed with car chases, gunfights, sci-fi spectacle, and surreal romance", while a new advert has since been released online showing "randomly chosen shots" which warns viewers to "unexpect the expected".

Ben doesn't want to divulge much more, but he says: "It's like a midnight movie. It's like something you would have seen on Channel 4 in the late 1980s by accident and you've missed the titles, you don't know what it is and then you spend the next 10 years trying to find out what that amazing film was."

The Bradford screening will take place at the Pictureville cinema on Saturday and be accompanied by a Q&A with Ben, stars Sam Riley and Alexandra Maria Lara, and producer Andrew Starke.
