The delayed echoing effect that is heard when a character is speaking directly into the microphone for Maureen's protest does not occur on the DVD if you have a mono television soundtrack.
The two disc DVD features an alternate ending where we find the main eight cast members back on the stage singing the last number. Although the number bookends the movie very nicely, and adds a shot of Angel missing from his spotlight, which is homage to the Broadway production, the concept was scratched for the current finale.
The "Without You" montage ended with a rather emotional scene of Rosario Dawson's character, Mimi, walking along a fence crying and singing the last verse of the song. In the editing room the scene was shelved. Additionally "Goodbye, Love" another emotional scene primarily focused on Dawson was also shelved. Upon release of the film Dawson's manager and lawyer contacted Colombus about cutting 'Dawsons' most powerful scenes' and were upset on the opportunities this may have cost her. The director gave his excuse that the first scene was cut in favor of a more "storytelling" scene of Mimi with Benny and the second was cut to maintain the emotional punch of the ending. Though Dawson's representation disagreed, no further legal action pursued. "Goodbye, Love" can be viewed on the two disc CD, whereas "Without You" remains shelved.
Mark's second act soliloquy number "Halloween" was filmed but director Chris Columbus never intended for it to make the final cut of the movie. The song, featuring Anthony Rapp walking solemnly through the graveyard, can be seen on the two disc DVD set.
