Mike Newell is returning to direct the special which was written by Red Nose Day founder Richard Curtis. James Fleet, David Haig, Sophie Thompson, David Bower, Robin McCaffrey, Anna Chancellor, Rupert Vansittart, Simon Kunz, Sara Crowe and Timothy Walker also star.
The special will be aired in Great Britain on Friday and will debut on NBC in the U.S. on May 23 as part of the network's Red Nose Day coverage. Red Nose Day is run by nonprofit organization Comic Relief Inc. which helps raise money and awareness to help children living in poverty around the world.
Comic Relief confirmed Vikander and James' involvement on Twitter Friday alongside a short teaser featuring Grant and Thomas reprising their roles as Charles and Fiona respectively.
Red Nose Day will also feature Jennifer Saunders parodying Mamma Mia! Here We Go Again.
