Keri Russell kept her lips zipped on Tuesday’s episode of Global’s “The Late Show With Stephen Colbert”.

The actress, 43, appeared on the hit late-night talk show to chat about her new Broadway show “Burn This”, but Colbert was more interested in another project.

The host decided to focus only on getting spoilers out of Russell about the upcoming “Star Wars: Episode IX” film. But sadly for Colbert, and “Star Wars” superfans, Russell didn’t crack.

Since the only bit of info Russell let slip is that she has “the coolest costume,” Colbert decided to predict his own storylines.

First, he tried, “Your character is Yoda’s ex-wife Rachel. You run a profitable business on Tatooine, you and Yoda met on OkCupid and he said he was 6-foot-2.”

Or maybe she’s “Chewbacca’s stepsister, Chewbecky.”

But nothing seemed to get a reaction from Russell, except a bit of laughter.

“Star Wars: Episode IX” hits big screens Dec. 19, but catch “The Late Show With Stephen Colbert” weeknights at 11:35 p.m. ET on Global.
