Knocked Up (2007)

 27 Dresses, The Ugly Truth, One for the Money – as a rule Katherine Heigl doesn’t make terribly good films. Luckily, this warm-hearted comedy by Judd Apatow is an exception. She stars as a journalist who finds her life plans in jeopardy when she becomes pregnant after a one-night stand with a likeable slacker, played by Seth Rogen (in the role that made him a bona fide star). In 2012, a spin-off sequel, This Is 40, was released.
