Just looking at Paul Rudd it's hard not to smile. Not only is the 46-year-old funnyman the star of some of our favourite films (This is 40, Wet Hot American Summer, Anchorman, I love you, Man, Clueless… we can go on and on!), but he's also a kind and loveable person who puts his family at the centre of his world.

Paul may be known for playing hilarious characters, many in Judd Apatow films, but the Kansas City-raised actor found one of his first roles in the theatre - portraying Hamlet in a production directed by none other than Sir Ben Kingsley.
From there the Ant-Man star's career picked up momentum fast (while doing some Bar and Bat Mitzvah DJ'ing on the side), breaking out in the way-cool 1995 cult-favourite Clueless and following up with Romeo + Juliet and The Cider House Rules before catapulting to comedic royalty.
The actor has, no doubt, endeared many a costar, including This is 40 leading lady Leslie Mann, who told Elle, "I can sit and listen to him talk for hours. He's pleasantly neurotic. He's really good-looking, but he behaves like somebody who isn't." And while the whole world seems to love Paul as much as his Hollywood contemporaries, he's only got eyes for one woman - his wife of more than a decade, Julie Yaeger (with whom he's been together for 20 years). The two have a son, Jack, and daughter, Darby.

The former InStyle Man of Style is also well-known for his youthful appearance (Paul just will not age!). He told the fashion magazine "I'm a big believer in sunscreen. I'm not one for tanning. I used to be, back when I was rocking the Depeche Mode look."
