The biggest comedy of March is sure to be Get Hard. It brings in the legendary Will Ferrell to spar with current box office champ Kevin Hart in what could be an instant classic. After the debut of the first two trailers earlier in the year, Kevin Hart used his own personal Faecbook to launch the new restricted trailer. Warning: This latest footage may be too filthy and too funny for anyone under 18 to handle!

When millionaire hedge fund manager James (Will Ferrell is nailed for fraud and bound for a stretch in San Quentin, the judge gives him 30 days to get his affairs in order. Desperate, he turns to Darnell (Kevin Hart) to prep him for a life behind bars. But despite James' one-percenter assumptions, Darnell is a hard-working small business owner who has never received a parking ticket, let alone been to prison.

Together, the two men do whatever it takes for James to "get hard" and, in the process, discover how wrong they were about a lot of things - including each other. Also starring Alison Brie, T.I., and Mariana Paola Vicente, Get Hard is the perfect kickstarter for Spring Break 2015.
