15 Movies You Won’t Believe Are 10 Years Old

8. Knocked Up

Looking back at it now, it's pretty shocking to have to accept that the film that put Seth Rogen in the window as a comedy lead (he'd been in The 40-Year-Old Virgin, of course but only as interesting support) is 10-years-old. Considering he and co-star Paul Rudd have clearly signed some sort of immortality bond with the devil (and aged not a day since), it's pretty hard to accept.

Or maybe it might be down to the fact that Katherine Heigl - at this point heading towards the top of her game as one of the go-to hires for a certain kind of rom-com after breaking out in Grey's Anatomy - hasn't worked nearly as much as you'd have predicted she would in 2007.

She's made only 11 films, and starred in two cancelled TV shows amidst a swirl of rumours that she's "difficult" to work with. As if to offer something of a soft confirmation immediately, Heigl called Knocked Up - the film that turned her into a blockbuster success - sexist and "hard to love".
