Victor Maynard (Bill Nighy) is an erudite, posh gentleman who also happens to be a professional hit man. Hired to terminate Rosie (Emily Blunt), a pretty young thief, he instead falls for her. On the run from the men who hired him, they are accompanied by a confused stoner (Rupert Grint) as they hide out till the coast is clear.
I always enjoy the wonderful Bill Nighy and he has many witty scenes early on; unfortunately, none of them are shared with Blunt or Grint. Blunt's character is thoroughly unlikable and she has no romantic chemistry with Victor; Grint's drifter serves no purpose in the story, he's awkward, and mumbles his dialogue. The film starts out promising enough as we watch Victor alone, but once the three come together it's absurd and silly.
This is an okay rental, just don't expect big laughs or a plausible script.
