While he’s remained working hard behind the scenes on upcoming films like the ‘Suicide Squad’ and the highly anticipated ‘Bad Boys III‘, Will Smith has been relatively quiet the past few years; in comparison to his usual level of work, at least.

But that all changes today with the impressive looking new ‘Concussion’ trailer, featuring the legendary Fresh Prince in one of his most serious roles to date. Starring as Dr. Bennett Omalu, the man who first discovered the now infamous CTE brain disease, Smith puts the NFL squarely in his targets in this new film. The trailer is explosive, and this is one storyline that has largely been swept aside by both the sports media, and their counterparts at large. A timely film that looks sure to generate some controversy, this new trailer is intense, and looks like it contains the makings of a great film. Check it out below.
