I just watched Collateral - a Michael Mann (Starsky & Hutch, Miami Vice, Last of the Mohicans, Manhunter, Heat) film staring Tom Cruise and Jamie Lee Fox.
I can't say enough about it, and won't. This review at IMDB pretty much sums it all up. Its simply Tom Cruise and Jamie Fox's best roles and a much better movie than Jamie Fox's other lauded role of 2004, Ray. Fox, for what its worth, has also been picked to play Det. Ricardo Tubbs in Mann's big screen adaptation of his famous TV show, Miami Vice.
If you haven't seen it, do yourself a favor and rent it tonight.
