Answer
The Life Aquatic does not feature Michael Palin. This is because the film was directed by Wes Anderson, who often collaborates with a different group of actors, including Bill Murray, Owen Wilson, and Jason Schwartzman. Palin, on the other hand, is a member of the Monty Python comedy troupe and has appeared in many of their films, including Monty Python and the Holy Grail and Life of Brian.
