Daniel Radcliffe First Paycheck $320,000

Daniel Radcliffe First Paycheck $320,000, July 23, Radcliffe's 18th birthday, will be a magic day for the star of the Harry Potter movies: He'll gain access to his $19 million investment fund – which he's socked away in a company jointly held with his parents Alan, a literary agent, and Marcia, a casting director.

But with two more movies still to go – for which Radcliffe will be paid a reported total of $50 million – he can conjure up plenty more golden galleons where that came from. British newspapers have estimated that Radcliffe currently has a total net worth of $35 million or more, making him the U.K.'s richest teen.

FIRST PAYCHECK: $320,000 at age 11 for the first two Potter films.

BIGGEST SPLURGE: He recently dropped $17,000 on a custom-made Savoir mattress. But come his landmark birthday, "I don't think I'm going to do anything particularly exciting," says Radcliffe, an only child who lives with his parents in London.

"People seem to expect me to splash out on a classic-car collection, but I've never been into cars or anything like that." He's more into cricket, theater (he shed his clothes for a recent turn in Equus in London), reading (lately Nabokov) and painter-sculptor Jim Hodges. "I know I'm lucky to be paid all this money to do what I love," he said in Britain's Daily Mail, but "[money is] not something that affects the way I think about things."
