The Mitchells - The Full Story, a one hour special, will air on UKTV Gold as part of the channel's Mitchells Weekend on March 25 and 26.
The weekend, timed to coincide with Grant Mitchell's return to Walford, will include classic Mitchell episodes such as the shooting of Phil, 'Sharongate' and the brothers' first episode.
The documentary is being filmed at Elstree and aims to "capitalise on Mitchell mania" with a look at some of the family's most memorable moments.
"The appetite for the soap's most notorious family will be at its peak at this time," said UKTV Gold commissioning executive Diana Howie. "This show will do brilliantly."
