It's a split decision for Luke's Super Ex-Girlfriends; MY SUPER EX-GIRLFRIEND (12A).

ASK Luke Wilson what kind of a superhero he'd be and he'll tell you what every woman wants to hear.

"I think I'd want to be 'Super- Understanding'," he says slowly but firmly, considering his options. And his costume? "Some flannel pyjamas and tights."

Unfortunately, in Luke's latest film, My Super-Ex Girlfriend, only his costar Uma Thurman gets the superpowers.

At 34 the Texas native is the youngest of his actor siblings - the slightly more famous Owen and rather less famous Andrew - and has appeared in Charlie's Angels and Legally Blonde?

My Super Ex-Girlfriend sees him playing Matt Saunders, a regular guy who dates Uma Thurman's sexy superhero G-Girl. Until, that is, he dumps her and all hell breaks loose.

Luckily Luke's own relationships, which have included Drew Barrymore and Gwyneth Paltrow, have ended comparatively smoothly. "I've been lucky in that I haven't had any really fiery break-ups," he confides, before admitting that his brothers have been less fortunate.

"Andrew, he had a girlfriend who lit some newspaper on fire and threw it into the sunroof of his car," Luke recalls. "That was pretty crazy - and it was Owen's car."

THIS movie's intriguing premise - about a guy who tries in vain to break up with his clingy superhero girlfriend - is ripe with comic potential, but there's no palpable screen chemistry between its stars Uma Thurman and Luke Wilson. **
