Whoo, boy. The Fox action-comedy “Knight and Day” has a trailer. And it’s a surprisingly enjoyable experience watching Tom Cruise step back into likable human terrain.

This is how a trailer should be done. It’s electric. It introduces the characters effectively, as well as establishes their chemistry. It blows some shit up. And it hints at a plot without talking the thing to death and obliterating any chance at surprise when you finally sit down to see the thing.

Not to hammer “The Bounty Hunter” too much, but contrast this trailer with that one and note the vast difference in appeal.

Anyway, this trailer does exactly what it’s supposed to do and sets up a fun action ride to look forward to next summer.
