The filmmaker says it took the right idea and a lot of money for the fake band to reunite for Spinal Tap II: The End Continues.

Like the original This Is Spinal Tap, Reiner has said that the sequel would largely be improvised, but with a firm structure in place. The filmmaker also cited another key influence of the film, saying it would be modeled in part on Martin Scorsese’s classic documentary about the Band’s final concert, The Last Waltz.
