Television actress Jena Sims just got her big break. The 23-year-old beauty queen (Miss Georgia Teen USA, 2007) is set to star in Roger Corman’s Attack of the 50-Foot Cheerleader, an EPIX original movie set to premiere Aug. 25.

Sims, a guest star on “The Vampire Diaries” and “Dexter,” plays a awkward college coed who turns to an experimental drug in the hopes of becoming popular and beautiful. Things go bad, however, when side effects kick in and she suddenly grows into a 50-foot giant (hey, it’s better than anal leakage).

Attack of the 50-Foot Cheerleader is directed by visual effects guru Kevin O’Neill and costars Hollywood psycho Sean Young, old-people actor Treat Williams, Ryan Merriman (The Ring 2) and horror hotties Ariana Madix (The Dead Want Women), Paula LaBaredas (Camel Spiders), Sasha Jackson (Tarantula), Olivia Alexander (Killer Eye: Halloween Haunt).

Caity Lotz is set to star in Content Film’s The Machine, a romantic sci-fi thriller directed by Caradog James (Little White Lies) about a scientist (Toby Stephens) who falls in love with the robotic soldier (Lotz) he’s creating for Britain’s Ministry of Defense.

The film’s official synopsis reads:

Set in the near future and with the world plunged into another cold war, Britain’s Ministry of Defense is on the verge of developing a robotic soldier. This soldier, called The Machine, looks and sounds human, but has the strength, speed, and ruthlessness beyond that of any living person.

The project is near completion when a bug in the programming, a side effect of it being too close to human coding, causes the prototype to destroy the lab and everyone in its path in spectacularly violent fashion.

Undeterred by this setback, lead scientist Vincent McCarthy obsessively continues his work on The Machine in secret, away from the prying eyes of those who seek to destroy him.

Lotz is an up-and-comer best known for her recurring role as Stephanie, Anna Draper’s niece, on AMC’s “Mad Men” and for playing Officer Kirsten Landry on MTV’s short-lived horror-comedy show “Death Valley.” She currently stars in writer/director Nicholas McCarthy’s creepy ghost story The Pact.
