Funnyman Jim Gaffigan is transitioning to dramatic roles.  Beginning with last year’s “Collide,” the standup comic has been proving that he possesses dramatic prowess needed for heftier roles.  This year, he’s starting off with the fantastic sci-fi dramedy “Linoleum” about a children’s science TV show host who decides to build his own rocket.  But what he discovers is far more deeper – the nature of reality and the discovery of happiness.
