Remember that two-part Skins episode called Pure that aired back in 2013? OK, good. Remember the character Jakob? Well, he was played by none other than Olly Alexander. Watching this back, we couldn't believe it either!
Turns out, he auditioned for a role in the show when he was 16, and didn't make it into the cast until he was well into his 20s. It just goes to show that perseverance pays off.
