TORONTO, CANADA - A kiss is sometimes just a kiss, unless it's Adrien Brody smacking Halle Berry's lips after his Oscar win in 2002 for "The Pianist" or his latest smooch with co-star Rachel Weisz in "The Brothers Bloom."

The film is premiering at the Toronto film festival this week.

"He's a wonderful kisser," Weisz told a press conference Tuesday of Brody. Their tongues were intertwined in an enthusiastic buss in a memorable scene in the film, she said. "It wasn't any old on-screen kiss."

"We needed a lot of rehearsal," commented Brody. "It was something we had to get just right."

"Unfortunately, he had to rehearse (it) with me," quipped director Rian Johnson ("Brick", 2005).

The romantic comedy follows two con artists (Brody and Mark Ruffalo) who take a beautiful and eccentric New Jersey heiress (Weisz) on a romantic adventure around the world.

Weisz ("The Constant Gardener", 2005; "The Mummy",1999) portrays the titular brothers' innocent mark with "child-like enthusiasm that I'm sure (audiences) will adore. And so it wasn't difficult for me to play a man falling madly in love with her," said Brody.

Audiences are said to be starving for a good adult romance film of late. Indeed, there are only a handful of films that arguably fit into the film festival's romance category this year.

"It's been a long time since there's been a real dramatic or tragic love story, a story of two souls uniting," commented Brody.

"Maybe we're just afraid of love," opined Ruffalo.

A self-described "big softie," Johnson announced he fell in love with a Serbian woman in Belgrade where the film was largely shot.

But to capture that "lightning in a bottle, the chemistry between two people, that spark is difficult to get. It's a rare thing to capture" on screen, he said.
