Isla Fisher looks set to be the leading lady in a new romantic comedy about a woman able to tell how a relationship will pan out by the quality of the first kiss.

The actress, who grew up in Perth and will soon marry Sacha Baron Cohen, shone as a crazy bridesmaid in Wedding Crashers with Vince Vaughn and Owen Wilson and is known for her comedic ability.

Up in the Air Oscar nominee Sheldon Turner will co-produce the flick, to be called Kiss and Tell, according to Variety.

Fisher has carved a career by choosing quirky characters in humorous flicks.

She starred in Defninitely Maybe opposite Ryan Reynolds, Confessions of a Shopaholic, Scooby-Doo and Wedding Daze.

Kiss and Tell looks set to continue this pattern, with her character possessing the gift (or curse) of knowing from that first pash whether a relationship will work out.
