I've waited to respond just to see what everyone else had to say. First, let me tackle Landers. She could not dance, why cast anyone in a movie where dancing is the first requirement. Let it be known that the current B'way Val at that time(DeLee Lively) was originally considered for the movie Val, but once they picked Landers, Lively was then only offered to be her dance double. Lively, of course, turned it down.
There were numerous B'way cast members that appeared in the movie; but no original members. Vicki Frederick(Sheila, B'way - Cassie); Pam Klinger(Maggie); Gregg Burge(Richie); Justin Ross(Greg); Matt West(Bobby); Yamil Bourges(Diana, International tour '90-'96); Blane Savage(Don; various tours/regional theatres '95-'01 as Zach). Several B'way cast members also appeared as cut dancers: Scott Wise(Mike), Cheryl Clark(Cassie), Buddy Balou(Mike, Al), Timothy Scott(Mark), Melissa Randel(Judy), Scott Plank(Larry), Niki Harris(Val, Sheila), Roxanne Caballero(Diana).
The movie isn't the worst movie musical every made. There are some bright spots - Frederick, Bourges, Burge. I actually didn't mind the addition of "Surpise" and the opening, although very 80s, worked. The movie failed once Mike started swinging from ropes. Then was saw "At The Ballet" get cut down and the "blitz" removed, "Sing" got cut. Connie, Greg, Mark, Don & Judy all get their solos cut as a result of "Surprise" and only get a very short monologue making their characters almost non-existent.
Landers actually made "Dance: Ten, Looks: Three" work, but then M&TM gets replaced by "Let Me Dance for You" and completely fails to get Cassie's message across. Then we have Cassie singing "What I Did For Love" by herself. Again, failing to get the message across. I don't think it mattered in the end who Zach picked, because did you really care who he picked?? As much as I feel the movie opened the eyes of some people who may never get to see a professionally staged version, it simply did not deliver the correct message about what A Chorus Line is, and should be.
A Chorus Line revival played its final Broadway performance on August 17, 2008. The tour played its final performance on August 21, 2011. A new non-equity tour started in October 2012 played its final performance on March 23, 2013. Another non-equity tour launched on January 20, 2018. The tour ended its US run in Kansas City and then toured throughout Japan August & September 2018.
