IMHO, no compensation or phone call is warranted. The FA's did what they could to make people comfortable (played movie) and I can imply that the plane had A/C and people had access to the bathrooms and their cell phones else there would be complaints about generalized mayhem.
FWIW, UAL Cargo says the cause of the delay was "operations". They left the gate about 20 minutes late at 6:02p... FlightAware says they didn't take off until 8:02p.
