Coleman Metts (CAS) was mixing on location for the film "Bobby", starring Martin Sheen and Helen Hunt. The scene involved the two main stars playing tennis, and Shia LaBeouf and Brian Geraghty are playing two guys high on Acid, trying to play tennis on the next court, disturbing Martin Sheen and Helen Hunt's characters. Coleman wired all 4 of the talent with SM transmitters. The actors started fighting, jumping over the net, and fighting around on the ground!
The audio was great, and after the take was over, the equipment was still in great shape. Shia LaBeouf, and Brian Geraghty mentioned they forgot they had the wireless stuff on!
