Writer and lead comic actress Amy Schumer couldn’t ask for a better feature film maiden voyage vehicle than Judd Apatow’s Trainwreck (B), a screwball character study shrouded in rom com clothing. Schumer’s central character is a boozy and sexually liberated magazine writer who meets her match in a well-grounded sports physician, warmly and effectively played by Bill Hader. Both Schumer and Hader are unconventional casting choices; and honestly, I wasn’t entirely convinced of their chemistry despite lived-in performances. But the film packs a comic punch with jabs at the mores of modern dating and has moments of poignancy in the heroine’s relationship with her misanthropic papa. There are shades of Pretty Woman and Bridesmaids as the film navigates some typical narrative arcs, and “Apatowesque” will now just be my adjective for overlong comedies. But as a sassy star is born, her film is a filling and funny frolic.
