B.K.
Forgive me, but as worded, your question of the day is a bit unclear.
Are you talking about movies that were produced in the 1980s and 1990s that later became musicals?
Or, any musical (adapted from a film) that was produced in that time period?
Not sure if they fit into your time period, but the only two musicals that I can think of that were based on previously produced films are CHICAGO and THE PRODUCERS.
Of course, ROXIE HART (CHICAGO) was, I believe, produced back i the late 1930s or early 1940s, so I don't know if that would count.
