Jon Hamm & Keri Russell Try Not To Laugh During 'Mad Lib Theater' with Jimmy Fallon!

Keri Russell and Jon Hamm both made an appearance last night’s (December 11) The Tonight Show Starring Jimmy Fallon, and participated in a hilarious round of Mad Lib Theater!

The 43-year-old Star Wars actress and the 48-year-old Richard Jewell actor had to say random words to fill in the blanks for a scene that they would perform together alongside host Jimmy.

In the scene, Keri, Jon and Jimmy acted out an exaggerated scene on an airplane as flight attendants and found themselves holding back laughter with some of their chosen words.

Jon Hamm also hit the couch to pitch a Star Wars role for himself, drops updates about working with Tom Cruise on Top Gun: Maverick and describes what it was like being directed by Clint Eastwood in Richard Jewell.
