The Flash and Supergirl Cast’s Talk Musical Episode in New Video

The CW has released a behind the scenes look at the music from last night’s musical episode of The Flash. In the featurette, the cast talk the big numbers filmed in the episode, preparing for it and so much more.

What did you guys think of the musical episode? It definitely had its moments, but was I the only one who felt as if the ADR was synced right. At certain points the audio wasn’t matching up with the people talking and/or singing.
