CNN:

During a recent rehearsal of Pretty Woman: The Musical attended by a handful of reporters, production stage manager Thomas Recktenwald ran lines with three cast members subbing in for an evening performance. Swiping through the ProductionPro app on an iPad Pro, Recktenwald showed off recent changes made to the script. It had notes scribbled into the margins via an Apple Pencil, and he tapped his way through videos that highlight blocking, broken down scene by scene.

Always interesting to see how tech is replacing some of this old school stuff.
