Revenge of the Sith would’ve beaten Titanic if it includes:

Stuff from the illustrated screenplay (Deleted Content)
The Siege of Mandalore Arc (So we can have the debut of Ahsoka, Rex, Bo-Katan, Rex, Almec, Gar Saxon, Rook Kast, Ursa Wren, Mandalore, and the syndicates. We can also have Maul return as well.)
The 2D Clone Wars’ Battle of Coruscant (This time in live action so we can see Greivous kidnapping the Chancellor and the live action version of Roron Corrob, Foul Moudma, Fordo, and other stuff)
Fallen Order (We can have a live action version of Cal Kestis, Jaro Tarpal, Cere, and Trilla)
Fan scenes from NV II (We can have Darth Plagueis, Darth Sion, Darth Bane, Darth Revan, Darth Teneborous, Darth Desolus, Darth Malygus, Exar Kun, and Marka Ragnos.)
