Ashton Kutcher, Katherine Heigl slay in 'Killers' trailer

We know what you're thinking. Please, no. Not another lame romantic comedy. 

But this one has real promise --- with touches of "Mr. and Mrs. Smith."

"Valentine's Day" Ashton Kutcher and "Knocked Up" star Katherine Heigl are actually very cute together in this preview. The story goes like this: A woman (Heigl) meets her ideal man (Kutcher), while vacationing in the South of France. Yeah, been there, done that.
