Stephen Hawking is an undeniable genius, but Eddie Redmayne and Kevin Costner had to learn the scientist's other quirks the hard way.
Both actors stopped by Tuesday's Jimmy Kimmel Live and discussed meeting Hawking. Redmayne, who plays the iconic physicist in the Oscar-nominated The Theory of Everything, said he was a rambling, sweaty mess when talking with Hawking -- whom Redmayne calls a true "ladies' man."
Costner backed up Redmayne's theory, telling about a time when Hawking requested to come to Costner's home and immediately asked him about his 1992 The Bodyguard co-star Whitney Houston.
