Four days after Sony slotted the Cameron Diaz-Jason Segel comedy Sex Tape for July 2, 2014, Warner Bros has lit the fuse on a potentially explosive faceoff with Melissa McCarthy. The Identity Thief star’s latest road-trip raunchfest Tammy will hit theaters that same Independence Day weekend, setting up an intriguing showdown. McCarthy stars in the New Line pic as a woman who loses her job and discovers her husband is cheating, then hits the highway for a bout of self-discovery along with her grandmother, a cussin’, diabetic boozehound. Mark Duplass last month landed a key role in the flick, which was written by McCarthy and hubby Ben Falcone; the latter stepped in as director for TV veteran Beth McCarthy-Miller, who was to make her feature helming debut. Tammy also stars Kathy Bates, Susan Sarandon, Allison Janney and Dan Aykroyd.
