Correct, it is Deja Vu.
To be honest, Denzel is hit or miss with me. While he definitely won't make the film, he really won't harm it either. Deja Vu also stars Val Kilmer and Erika Alexander, who I love, so I took a chance.
The thing that made Deja Vu work for me was the Sci-Fi twist -- specifically the "limitation" they had to work with. I enjoyed that little gimmick.
