"When we saw Samara and Brigette together, it was like deja vu," producer Scott Kroopf said in a statement. "It was exactly the way we felt when we first saw Keanu [Reeves] and Alex [Winter]. We are so thrilled to have this funny and unique pair join the Bill and Ted team!"

This casting follows on the heels of a tease dropped by Reeves in February. "I'm sure they can't help but have a bit of their mothers and fathers in them. So we'll see how that expresses itself," the John Wick star hinted at the time.

In this film, Bill and Ted introduced their chidren as "little Ted" and "little Bill" respectively, suggesting they also have sons.
