Jared Leto – Age 51

Anyone who watched “Suicide Squad” in 2016 remembers the eccentric “Joker,” played by Jared Leto. Jared is a very committed actor who once lost 28 pounds to star as a heroin addict in “Requiem for a Dream” and added 60 pounds to play assassin in “Chapter 27” in 2007.

Even though he has won an Oscar for his performance in “Dallas Buyers Club,” Jared is also a musician, having formed the alternative rock band “30 seconds to Mars” with his brother with songs like “Walk On Water” and “Attack.” Jared has since shown himself to be one of the most committed and versatile stars out there, and we totally agree.
