According to various websites the following is an ad for Chevy and Transformers: Dark of the Moon that will air during the Superbowl this Sunday.
Originally, I found this on Youtube, but then it seemed to be made for "private" viewing only.
This 30 second spot comes courtesy, MovieWeb.com.
Doesn't look bad.
Transformers: Dark Of The Moon hits theaters July 1st, 2011 directed by Michael Bay and starring Shia LaBeouf, Rosie Huntington-Whiteley, Julie White, Kevin Dunn, Josh Duhamel, Tyrese Gibson, Alan Tudyk and John Malkovich.
