The long-awaited and much anticipated fifth installment to the "Underworld" franchise has officially started production in Prague this week with the principal photography.

According to JoBlo, the film has begun the first of the anticipated 10 weeks of production at various locations in and around Prague for what is hyped to be one of the most climatic films in the series, which includes returning stars.

Anna Foerster will be taking the helm in this film, which will mark her directorial debut. She previously worked on "White House Down" as a cinematographer and fans are excited to see how she will represent the cherished franchise in this next movie.

Although a synopsis for the film has not been released yet, the script was written by Cory Goodman ("Priest," The Last Witch Hunter") and there have been a few details that fans may have already assumed.

First of all, Michael is expected to be returning to this film, but it is unclear if the original actor for the character, Scott Speedman, will be reprising the role or if he has been recast. His character made brief appearances in the previous film, "Underworld: Evolution," but the actor's face was hard to see at most parts. The IMDb page listed him as the portrayal in the film, but it was with archival footage.

Fans can expect the storyline to continue with Selene (Kate Beckinsale) pursuing Michael after he was broken out of his cryogenic prison. They now have a daughter to take care of and she will likely be pursuing him across continents to bring their family back together.

Returning to the franchise film are Beckinsale, Theo James and Charles Dance, who played the coven master Thomas in the previous film.

Some new names to the franchise are Tobias Menzies, Bradley James and Clementine Nicholson for the Lycans. For the Vampires, fans will get Lara Pulver added to the cast as a fiercely ambitious warrior. It is unclear if she will play a nemesis role to Selene or if they align.

"Underworld: Next Generation" is set for release on Oct. 21, 2016.
