"Leaving in a few hours for UK for 2 months to act in Rifco Arts' 'Happy Birthday Sunita'. Wish me luck friends. Theatre is a different ballgame," Azmi posted on Twitter.
Rifco Arts has previously produced plays such as 'Britain's Got Bhangra', 'Break The Floorboards' and 'Deranged Marriage'.
Besides Azmi, the play also has actors Ameet Chana, Russell Floyd, Clara Indrani and Goldy Notay.
