I’m in Chicago, where it’s the first day of tech rehearsal for Big Fish. Lights, sound, sets, props, costumes, VFX — everything has to be painstakingly tweaked and coordinated. In film terms, it’s like production and post-production happening simultaneously.

In other words, it takes a while.

Quite fittingly for a day of slow motion, EW.com has the exclusive first listen at a song from our show: Time Stops. It’s a duet between Norbert Leo Butz (as Edward Bloom) and Kate Baldwin (Sandra), written by Andrew Lippa.

If you’re familiar with the movie, you can probably guess where this song takes place, but I won’t spoil how it actually emerges in the scene. Suffice to say we’ll be spending many hours of tech getting it just right.
