VIDEO : Oscar Isaac Will Never Forget Being Repeatedly Slapped By Carrie Fisher

On the 40th anniversary of Star Wars: Episode IV: A New Hope, new Star Wars Star Oscar Isaac dropped by The Late Show with Stephen Colbert to discuss The Last Jedi and what it was like to get beat up by Carrie Fisher. Before she tragically passed away last December, Isaac filmed a ?large amount [of] stuff? with Fisher. Isaac said in the interview, ?I remember the first day of shooting was a scene with Carrie.? Isaac praised Fisher for being ?by far the quickest-witted, funniest, most down-to-earth, real human being [I] ever had the opportunity of working with."
