LOS ANGELES — Road-trip movies have been dominated by teenagers on wild adventures or “Hangover”-style bromances, but Barbra Streisand and Seth Rogen are driving the genre into new territories with mother-son comedy “The Guilt Trip.” The movie, which hits US theaters this week, follows struggling novice inventor Andy (Seth Rogen), who is guilted into bringing his mother on a work-related road trip across the country. Streisand, 70, who broke out as an actress in 1968's comedy “Funny Girl,” returns to her comedic roots as Joyce, Andy's overbearing mother, who becomes closer to her son over the duration of their tense and comedic adventures on the road. — Reuters
