As part of its promo for the upcoming Transformers DVD (the boxes with the Bumblebee mask, the Optimus Prime mask, and the Transforming Megatron), Wal-Mart are showing behind-the-scenes videos from the set of Transformers 2.

The first video you’ll see is footage from the first day of filming at Bethlehem, Pennsylvania, and the second video shows how ILM created the robots in the first film.
