before the release of revenge of the sith on both film screen and digital, rick m. said the digital version was going to probalbly be closer to the dvd and have the yoda landing on dagobah scene, a more finished version. of course we know the film/ digital are identical, rick said they "might" Put a longer version out there in digital cinemas. Of course with lucasfilms planning of 3-d versions of all six films the revenge of the sith imax was cancelled early on. They said attack of the clones imax did'nt make enough money to warrant a release of sith in that format. from what i know of the imax most showings were sold out and it made tons of money, so when rick said it did'nt make enough money he was bullshitting us all.
