For only the second time (its first being with The Critic) in 25 seasons, The Simpsons will be part of an official cross-over episode, this time with Family Guy. Comic-Con 2014 attendees got an early taste of the episode on Saturday 26 July – and now it’s our turn to check out the five-minute sneak preview

In the special hour-long episode, The Griffins family become sidetracked and find themselves in Springfield, where they make fast friends with The Simpsons based on their obvious similarities. The episode is said to be aired in the US on September 28 2014.

‘I believe that this would do WAY better being a MOVIE!!! The Simpsons DOES seem to need something pushing it back out there.’
