I have a fondness for The Goonies just like everyone else around my age, but the thought of a Broadway musical adaptation kinda gives me the creeps. From EW.com:

The film's director, Richard Donner (16 Blocks), says there is an active attempt to mount a musical adaptation of the original, which was written by Chris Columbus from Steven Spielberg's story. ''Steven and I have discussed it, and it's something that I'm fairly passionate about right now,'' Donner tells us.

A second movie seems unlikely, however. ''We never had a script,'' Donner explains. ''We tried a couple of times and every time we did, we realized, 'What are we doing?'''
