The Mummy: Russell Crowe reveals Dr Jekyll's evil side in behind-the-scenes featurette

In the run-up to the film's release next month, Universal Pictures has released a new featurette for upcoming action adventure The Mummy, starring Tom Cruise. Not only does it introduce the Prodigium, a monster-hunting organisation run by Dr Henry Jekyll (Russell Crowe), it also reveals him transforming into his murderous alter-ego, Mr Hyde, for the very first time.

"The central character behind all of the events of the movie is Dr Henry Jekyll - famous for being Jekyll and Hyde," explains producer Sean Daniel in the clip. Crowe continues: "Jekyll operates a thing called Prodigium, which is essentially an organisation that pinpoints evil and tries to neutralise it.

"There's a lot to find out with Jekyll and it's not giving too much away to say that he has quite a clear understanding of evil," the Australian actor says.

The film follows Cruise's Nick Morton and Annabelle Wallis' Jenny Halsey as they travel to the Iraqi desert in search of an ancient tomb. However, the mission takes a life-threatening turn when they realise that by opening the crypt, they've exposed themselves to immensely powerful, supernatural forces. That's not all the pair and their exploration team have to worry about either as.

According to the production studio, the film will take audiences "from the sweeping sands of the Middle East through hidden labyrinths under modern-day London", while also "bringing a surprising intensity and balance of wonder and thrills in an imaginative new take that ushers in a new world of gods and monsters."

Not only did the featurette reveal the first glimpse at Jekyll's dark side (aka Hyde), it also appeared to tease future creature feature reboots in Universal's planned Monsterverse too. In a scene which takes place at Jekyll's Prodigium office within the Natural History Museum, Morton can be seen looking at a series of jars and in one, a fanged skull (like that of a vampire's can be seen). Dracula, anyone?

Written by Jon Spaihts (Prometheus), and directed by Star Trek's Alex Kurtzman, The Mummy also stars Jake Johnson, Courtney B Vance and Sofia Boutella as the titular villain and is slated to reach both UK and US cinemas on 9 June 2017.
