I want to know the answer to the following question:
What new footage did Columbia require for a Close Encounters revisit?
All the background I'm provided with is that "For this, Spielberg fixed some of the flaws he thought impeded the original 1977 version of the film and also, at the behest of Columbia, and as a condition of Spielberg revising the film, shot additional footage showing the audience the interior of the mothership seen at the end of the film (a decision Spielberg would later regret as he felt the interior of the mothership should have remained a mystery).". Is that enough to answer the question?
Answer: yes
