Gary Oldman is struggling to find funding for a passion project about photographer and cinema pioneer Eadweard Muybridge, because the film doesn't feature LEONARDO DiCaprio or zombies.

The Dark Knight star has spent the past two years seeking Hollywood funding for his movie, Flying Horse, but admits it's very difficult to get studio bosses interested even though he's involved.

Oldman tells Playboy, "Just financing a film, getting studios to part with their money (is tough)... I have my cast pretty much, but the funding isn't there. Partly it's the subject. If it had zombies and Leonardo DiCaprio in it, people would be falling over me."
