Jennifer Lawrence goes from sexy '70s femme fatale to blue mutant Mystique in newly-released X-Men: Days Of Future Past stills.

#askaroundnow
Jennifer Lawrence undergoes quite the transformation as she shapeshifts from '70s femme fatale Raven Darkholme to blue-skinned gun-toting Mystique in the latest instalment of the X-Men franchise, titled Days Of Future Past.
In new stills released ahead of the film's May 23 premiere, the 23-year-old dons two very different looks as viewers are taken back in time to the event that changed the course of history for mutants everywhere.
With a group of giant robots called Sentinels wiping them off the face of the planet, it's up to Wolverine to travel back 40 years in time to intervene and save them all.

Style chameleon: Jennifer Lawrence embraces her sexy '70s vixen as the action heads back to the time that fashion forgot in newly-released stills from the upcoming X-Men: Days Of Future Past movie

That's more like it: The star then undergoes quite the transformation as she's covered in head-to-toe blue body paint complete with scales, a slicked-back red 'do and yellow eyes to portray the gun-toting mutant Mystique

The Oscar-winning actress looks very much like her American Hustle character as she slips into a low-cut little black dress, complete with thick brown belt with large gaudy gold buckle and a long camel-coloured coat featuring white fur trim, and with her hair golden and styled in curls.
It's certainly in stark contrast to her bright red slicked-back locks, head-to-toe blue scaly body paint and yellow eyes when in her natural mutant form.
The gun-wielding image is apt considering it's her actions in assassinating a political figure that leads to the trouble in the first place.
Another behind-the-scenes snap shows Ellen Page being directed by Bryan Singer in her role of Kitty Pryde as she uses her powers to send Wolverine back to 1973. 

Coming in 2014: X-MEN: DAYS OF FUTURE PAST

On-set instruction: Bryan Singer directs Ellen Page as Kitty Pryde in this scene in which she transports Hugh Jackman's Wolverine back to 1973 to stop the event that jeopardises each and every one of their futures

Fans also get a glimpse of the return of Storm, played by Halle Berry, who hasn't appeared in an X-Men movie since 2006's The Last Stand.
Singer, who returns to the director's chair for the first time since X-Men 2 in 2003, has dubbed the latest movie an 'interquel' - neither a sequel nor a prequel.
'It's a new thing, as opposed to another X-Men picture. That part is challenging and kind of fun. The key is making something where the past and the future can intertwine, and there's a logic to it,' he explains to DenOfGeek.com.
Real-life couple Lawrence and Nicholas Hoult are also reunited in the film, with the English actor reprising his role of Hank McCoy, aka fellow blue-hued Beast.

Game Of Thrones favourite Peter Dinklage also stars with a very '70s hairdo and thick moustache in the flick as Bolivar Trask, a military scientist and creator of the Sentinel, which is dubbed 'the most advanced weapon since Oppenheimer'.
'Trask's agenda... he's very good at what he does. He sees humanity threatened, and he has the ability to protect it, so that's what he chooses to do...' Dinklage tells DenOfGeek.com.
Michael Fassbender also dons two decidedly different looks in the stills as he embodies the younger version of Sir Ian McKellen's Erik Lehnsherr, aka Magneto.
The Irish-German star looks rather suave in all black complete with sunglasses and a fedora as he struts along, before suiting up in his famed deep red armour as the all-powerful superhero.

Speaking to DenOfGeek.com about Wolverine's role in the film, Hugh Jackman explains how his character takes on the pivotal task entrusted to Kitty Pryde in the comics.
'I go back and find a younger Charles Xavier in a more vulnerable place, a slightly less wise place,
a difficult place where I can play the role for him that he would later play for me,' he reveals. 'It's poignant and beautifully brought out in the script.'
Speaking of the Professor, while he's not in these newly-released images, fear not, as both James McAvoy and Patrick Stewart return to play him in his younger and older incarnations respectively.
