Ash vs. The Evil Dead stars Bruce Campbell and Lucy Lawless appeared on the Late Show with Stephen Colbert last night and decided to share some acting tips with the world while waiting to go on.

Aspiring actors take note, Lawless played Xena Warrior Princess for six seasons and in recent years popped up in shows such as Spartacus and Parks and Recreation. While Campbell went from the iconic role of Ash in The Evil Dead franchise to playing 'Snooty Usher' in Spider-man 2 (still the only character to defeat the webslinger).

What these two don't know about acting isn't worth knowing.
