Actors Saiyami Kher and Regina Cassandrra will feature alongside superstar Sunny Deol in filmmaker Gopichand Malineni's upcoming action film.

Touted as the "biggest action film of the country", the untitled film will be produced by Mythri Movie Makers and People Media Factory.

Kher, known for movies such as "8 A.M. Metro", "Ghoomer" and "Choked", shared the news in a post on Instagram.

"Lights camera action! Time for some serious action. Can’t wait to fight it out along side, the one and only @iamsunnydeol. Really happy that @mythriofficial & @dongopichand sir have shown faith in me for an out and out mass action film. Let’s do this! Please wish us luck," the actor wrote alongside photos from the film's launch ceremony on Thursday.

"To new beginnings and new adventures! Kickstarting a very exciting project on an auspicious note with more than legendary company. #SDGM - directed by @dongopichand," she wrote.
