Mila Kunis has been pretty busy as of late thanks to the upcoming release of her film Oz: The Great and Powerful.

The 29-year-old attended several red carpet premieres around the globe to promote the film about a magician-turned-wizard, played by James Franco, who ends up in an enchanting world and meets three witches, one of which is played by Kunis. The film also stars Michelle Williams, Rachel Weisz and Zach Braff.

The Black Swan star known for her television stint on That '70s Show is on the cover of two magazines to promote the film. Kunis and her co-stars appear on the cover of the latest issue of The Hollywood Reporter and she posed solo on the cover of Marie Claire UK.

In her group interview she discussed the rigorous make-up process she endured for the movie- it took four hours to apply and an hour to remove.

"There were two big prosthetic pieces," Kunis told the Reporter. "Then you sort of get spray-painted with color, which gets glued to your skin. It damages your skin. The taking-off process makes it raw and swollen. It took two months for my skin to recover."

On the cover of Marie Claire UK's April 2013 issue, Kunis wears an all-white outfit and in the cover story she opened up about everything from That '70s Show to life in Hollywood. She said when she decided to pursue a career in film she "went on a mission to prove everybody wrong."

"I read for movies I would never do," she revealed. "I auditioned for everything, just to show I could do it. I needed to prove I was capable of doing things other than-forget comedy-other than a TV show."

As for her the changes that come with moving from a small town to Hollywood, she admitted that while the hardest part is being famous, it also has its perks.

"To say my life hasn't changed would be a lie," Kunis said"It has changed, I don't really know how. I can't complain, nor am I complaining, but I can't leave my house as freely as I used to. But I've also traveled a lot for work, so that's changed. I have been very lucky."

Oz: The Great and Powerful will arrive in theaters nationwide on March 8.
