Family Guy And The Simpsons: See Crossover Video
Trailer for historic collaboration episode includes masses of footage...
A special episode sees the Simpson and Griffin families meet up, make friends and fall out as the Griffins visit Springfield.
And running just short of five minutes, the trailer released by US cable channel Fox gives fans a sneak peak at several of the key scenes.
Peter and Homer are seen bonding over doughnuts and flying a biplane together (in a daydream), while Bart schools Stewie in prank phone calls and skateboarding.
But things turn sour after the two men fall out over the relative merits of their favourite beers, getting involved in an OTT Hollywood-style fight sequence which features a stolen school bus and a radioactive disaster.
The episode is set to air in September. More details to follow.
