Coming sometimes next summer, Mel Gibson is back in an action mode! In an upcoming thriller titled HOW I SPENT MY SUMMER VACATION (hmm, that sounds like a romantic comedy to me), Mel Gibson plays a lifelong criminal who is sent to a Mexican prison. He learns how to survive in the drug-infested jail with the help of a nine-year-old boy. Mel Gibson is also in charge for co-writing the screenplay and the movie is directed by Adrian Grunberg, who was a former assistant director for movies including 2006's APOCALYPTO and 2010's EDGE OF DARKNESS. In the meantime, check out the new poster below.
