The Simpsons to air first hour-long episode

Long-running US sitcom, The Simpsons is to broadcast its first hour-long episode next year.


Although there has been a Simpsons movie, this will be the first time a regular episode has run to an hour.


Executive producer Al Jean joked in a statement: "I just pray it won't be the last thing people see before a Trump inauguration."


Taraji P Henson, who plays Cookie on Fox's Empire, and actor and comedian Keegan-Michael Key will guest star.


Henson will voice the role of Praline, the former wife of a music mogul who has conned Mr Burns into bankruptcy, while Key will play Jazzy James, who joins Praline, Homer and Bart to help Mr Burns get his revenge.


The episode, which will go out in January in the US, will be titled The Great Phatsby, a play on The Great Gatsby.


The Simpsons begins its 28th season on September 25.
