Thirty-six years after leaving Welcome Back, Kotter, John Travolta is making his return to TV to play O.J. Simpson's attorney Robert Shapiro in American Crime Story: The People v. O.J. Simpson, and the actor admitted to ET that he has a lot to learn about the famous trial before shooting begins in the spring.

"To be honest, I have to investigate," Travolta told ET's Jason Dundas. "I have homework to do. [Shapiro] is an interesting character."
The 10-episode FX miniseries is based on Jeffrey Toobin's book, The Run of His Life: The People v. O.J. Simpson, and tells the story of the trial from the perspective of the lawyers. Shapiro was a key member of O.J.'s "Dream Team" of lawyers during the murder trial of Nicole Brown Simpson. O.J.'s high-profile defense team also included Johnnie Cochran, F. Lee Bailey, and Alan Dershowitz.
Travolta, who is also producing the project, will be joined by American Horror Story's Sarah Paulson, who stars as the prosecutor, Marcia Clark, Friends actor David Schwimmer, who will play Kim Kardashian's late father, attorney Robert Kardashian, and Oscar winner Cuba Gooding Jr., who will portray O.J.
"I do [think Cuba's right for the role]," Travolta told ET. "I think he's charismatic. He has the looks. He's played an athlete before -- a football player."
