Madonna's Greatest Acting Roles
I think she is not a horrible actress at all. She was really phenomenal in two films:
1. Dangerous Game (1993) - pure acing and no singing!
2. Evita (1996) - very emotional & touching "long music video"
Also, she was really good (or at least decent) in these films:
3. Dick Tracy (1990)
4. A League of Their Own (1992)
5. Desperately Seeking Susan (1985)
6. Bloodhounds of Broadway (1989)
And I really don't think she was that bad in:
The Next Best Thing (2000)
Body of Evidence (1993)
