Amy Schumer and LeBron James in Trainwreck.

Trainwreck offers the hilarious Amy Schumer her first starring vehicle, with a screenplay she wrote under the directorial tutelage of Judd Apatow. This movie signals the arrival of Schumer as a cinematic force.

She plays Amy, a magazine writer playing the field in New York—and doing it rather sloppily. When she’s assigned a story about a sports-medicine doctor (Bill Hader), she unexpectedly falls for him, which puts her plan to just fool around into flux.

Schumer crafted a run-of-the-mill romantic-comedy plotline with her screenplay, although it’s peppered with profanity that is sometimes beautifully shocking. She shows that she has the ability to nail the laughs—but she can also bring the emotional stuff, too. She has a funeral scene that is, dare I say, sublime.

Hader is his always-terrific self as the shell-shocked boyfriend who is just trying to bring some stability into Amy’s life, and Colin Quinn is terrific as her retirement-home-dwelling father.

The storyline is a little weak and predictable, but Schumer and Hader are awesome together, so that makes this very much worthwhile.

Trainwreck is playing at theaters across the valley.
