Is this a mockumentary?
I noticed in the past two years the director has made two other films. The first exposed the fact that Paul McCartney of the Beatles actually died in the 1960s and had been replaced by an impostor. The second film broke the news that Elvis was still alive.

Is Dreams from My Real Father the third in a trilogy of mockumentaries? Is Gilbert really yanking the chains of wingnuts? Or does he believe really Paul is dead, Elvis is alive, and Obama is a communist?
