okay just thinking out loud here, one of my ideas so far is to have the scene where baby lister is found under the pool table as a pre-credits opener. after the credits then use the bulk of tikka to ride, I was thinking of starting it with listers attempts to explain the end of series 5 coupled with some flashbacks, but having got through Tikka To Ride, I thought maybe I could start the movie with Lister appearing inside JFK's riot van saying "I have a very strange tale to tell" and then show the rest of the episode...
