Judd Apatow has released his trailer for This is 40<\/em>, the \u201csort-of\u201d sequel to his 2007 hit\u00a0Knocked Up.<\/em><\/p>\n The movie follows Pete (Paul Rudd) and Debbie (Leslie Mann) as they reach that dreaded 4-0. From the viewpoint of someone who may or may not be nearing that number, it looks pretty funny.<\/p>\n The trailer is below, but hear this warning. Like all Apatow movies, this one is rated R, hard R, like scorch your eyeballs R. So watch it with caution.<\/p>\n Judd Apatow is incredibly insightful and tells truth. His viewpoint can be shockingly conservative (as in the recently released Five Year Engagement<\/a>, <\/em>which he produced), but is told through his lens of gross-out, crude humor.<\/p>\n It\u2019s not for everyone. This is 40<\/em> hits theaters December 21.<\/p>\n
