The network will air a repeat of Fringe's penultimate episode at 9/8c Thursday and the Glee pilot Friday at 9/8c. During the airings, cast members and producers for both shows will tweet, and the messages will be simultaneously telecast in a lower-third scroll.
The tweets will answer fan questions, offer behind-the-scenes info from the episodes and tease the upcoming season.
Fringe producers Jeff Pinkner and J.H. Wyman, as well as cast members Joshua Jackson and John Noble, will handle the tweeting duties for their show while Lea Michele, Kevin McHale, Mark Salling, Cory Monteith, Amber Riley and Chris Colfer will all tweet Glee.
