I love Mary Poppins, Oklahoma!, The Producers, Annie (1982), A Star is Born, At Long Last Love (only for the Cole Porter songs and some of the actors), a guilty pleasure but an awful movie: Sextette. I totally love Singin in the Rain and Meet Me in St. Louis, and Best Little Whorehouse in Texas.
There are just way too many to pick one.
"Love the Art in Yourself. Not Yourself in the Art." -- Stanislavski
Cabaret- it's one of the few adaptations from the stage that includes aspects of the stage show, but includes its own aspects. I love it. It's not just the show on screen, a la Phantom and The Producers, it's unique.

The 1936 version of Showboat which is one of the most faithful reproductions of a stage musical. Irene Dunne had starred in the lead role of Magnolia, as had Paul Robesom, Helen Morgan and some of the lesser players. The score was pretty faithful and the most amazing this is it was done by Universal, a studio never known for its musicals. The producer, Carl Laemele Jr. retired, literally to his bedroom at age about 35 in disgust of the the way his father, Carl Sr. was treated and never made another film.
Argh, I have to go with a tie--"West Side Story" and "Rent". These are two that I do not watch frequently, but I was won over instantly when I first saw them and I never get bored when I do watch them. What I like about "West Side Story" and "Rent" is that, despite their imperfections, they are filled with emotion and color and urban beauty and life. They also feature excellent performances (Rita Moreno, George Chakiris; Wilson Jermaine Heredia, Jesse L. Martin, Rosario Dawson) that make you wish you knew the characters. Doesn't hurt that both have fantastic (albeit wildly different) music.
Also have to mention "Chicago", which is almost flawlessly executed and I can watch over and over. Others I really like but have issues with: "Cabaret" (it certainly stands apart from the stage show, but I wish they hadn't done away with quite so much music), "Hair" (kind of like "Rent", minus characters I care a lot about), "Phantom" (I went from loving it to hating it to realizing it was really quite good, aside from poor Gerard Butler being totally miscast and ruining a lot of what believability the story ever had).
"If there is going to be a restoration fee, there should also be a Renaissance fee, a Middle Ages fee and a Dark Ages fee. Someone must have men in the back room making up names, euphemisms for profit."

"For example, if I should paint my fingernails green -
and it just so happens I do paint them green. Well, if anyone should ask me why, I say: 'I think it's pretty!'"
west side story will always hold a special place in my heart because it was the first musical i ever experienced, and i was obsessed with it as a kid. It still gives me chills!
