Kutcher became That '70s Show's breakout star, making a name for himself in the comedy genre by starring in a string of funny flicks like What Happens in Vegas (2008), Killers (2010), and No Strings Attached (2011). He's also taken on more dramatic roles, including The Butterfly Effect (2004) and the 2013 biopic Jobs, in which he played the famous Apple founder.

He returned to the small screen in 2011 when he joined the sitcom Two and a Half Men, and more recently starred in TV series The Beauty. He also made a cameo appearance in That '90s Show.

Kutcher doesn't just rely on his acting career to boost his fortune. A savvy venture capitalist, he's the co-founder of A-Grade Investments and has poured cash into a range of start-ups. An early investment in OpenAI has significantly boosted his wealth, and his staggering fortune is pegged at around $500 million (£368m) – who's laughing now?
