Despite having been in the acting industry for a number of years it's only recently that Leslie Mann has really come to the attention of the cinema going audience.Leslie started out in commercials before moving into movies, landing role in The Cable Guy with Jim Carey and George of the Jungle with Brendan Fraser.However it's, like some many other actors, her collaborations with Judd Apatow, who happens to be her husband, that has thrust her into the limelight.The rise of the 'geek chic' movie, which has been led by Apatow and Seth Rogan, has mad stars out of many of cast member s who have become regulars in their movies.Leslie landed a small part in The Forty Year Old Virgin in 2005, which was directed and produced by Apatow. The film was a surprise hit going on to gross $177 million at the global box office.

But it was her role as Debbie Scott in last summer's Knocked Up where she really made her mark.

Alison has everything going for her after being promoted to in front of camera instead of behind at E! She goes out to celebrate with her older sister Debbie (Mann)

Not long into their celebration Debbie is called home to see to her children but Alison stays behind with Ben, a guy she met at the bar earlier that night. As the night continues the pair get more and more drunk and they end up back as Alison’s

But when morning breaks Alison discovers that Ben is an overgrown child with no money and no job. After breakfast they politely go their separate ways.

Until two months later after vomiting during an interview Alison discovers that the unthinkable has happened.

Leslie and onscreen husband Paul Rudd were also superb as the unhappy husband and insecure wife. They are the perfect and constant reminder to Alison and Ben how they don’t want their relationship to turn out.

Leslie will next star in Drillbit Taylor with Owen Wilson, which is also produced by Apatow, and then 17 Again with Matthew Perry and Zac Efron.
