The only two films that really have the same format are TESB and ROTJ, all the others vary. All 8 saga films end credits start exactly the same way. TMP has Duel of the Fates followed by Anakin’s theme. AOTC has Across the Stars. Both those end softly. ROTJ has Battle of Heroes and then comes back to the same ending as the OT. ANH didn’t really use the same theme pattern. It used Leia’s theme and the Star Wars theme (which Williams edited together to make the longer Star Wars theme from the original LP). TESB used Yoda’s theme and the Imperial March before coming back to the Star Wars theme to end. ROTJ also used themes and came back to the Star Wars theme at the end. The big difference between the PT and OT is that the PT used the theme recording and the OT had specific scored end credit recordings. From what I see, the ST has followed the pattern of the PT in ending softly. So 4 of the 8 end with the Star Wars theme ending and 4 of the 8 end softly. Well, I should correct myself. That is how they end musically. TPM ended with the Darth Vader breathing sound.
