Hollywood generally reserves that month for dramas, so action films released then don't face a lot of competition within the genre. None of the Fast & Furious movies were released in February, and if you're wondering, the sixth film in that franchise is due Memorial Day weekend, 2013.
Dreamworks wants to give Need for Speed a chance to get its own air, but the studio's February-release track record is pretty bad, with bombs like I am Number Four, Euro Trip, and Norbit. (A notable exception? Old School.) NFS director Waugh probably likes February, though. After all, Act of Valor was released that month, and it's the film that got him the job.
