Which comedian wrote and starred in the 2015 film Trainwreck?

Amy Schumer wrote and starred in the 2015 romantic comedy film Trainwreck.

The film was directed by Judd Apatow and follows Amy Townsend, a magazine writer whose commitment to a carefree single lifestyle changes after she begins dating a sports doctor. Schumer wrote the screenplay, drawing on themes associated with her stand-up persona while creating a fictional character rather than playing herself.

Trainwreck was Schumer’s first leading role in a major feature film. The cast included Bill Hader, Brie Larson, Tilda Swinton, Colin Quinn, and LeBron James. The film combined relationship comedy with workplace and family storylines.

The title can cause confusion because “train wreck” is also a common phrase unrelated to the film. In this question, Trainwreck refers specifically to the 2015 movie written by Schumer and directed by Apatow.
