In a turn of events that I had not expected, another Transformers veteran is set to return to the fold. Joining Optimus Prime’s voice actor Peter Cullen is Frank Welker. Frank Welker gave voice to Megatron and Soundwave among other characters in the original Transformers animated series. Fans have spoken up about bringing him on board and Michael Bay responded:
I think I’m going to pursue Frank on Soundwave.
A very succinct and exciting proposition. This movie just gets bigger and bigger all the time!
