Doctor Who The Impossible Astronaut (2009)

During a break from their travels with the Eleventh Doctor, his companions Amy and Rory are sent envelopes summoning them to Utah at a specific time and location. They arrive to meet River Song (who also received an envelope) and the Doctor, who is nearly 200 years older than he was when he last saw Amy and Rory. He offers them a picnic, and then a trip to "space 1969". During the picnic, a figure from the lake in an American astronaut suit shoots the Doctor multiple times and his body falls. A man called Canton Everett Delaware III arrives with a can of gasoline, telling Amy, Rory, and River that the dead man is the real Doctor. The Doctor's body is burned in a Viking funeral.
