Jon Favreau's 'The Jungle Book' adaptation is looking to add some star power as the film is in talks to cast recent Oscar winner Lupita Nyong'o and 'Captain America: The Winter Soldier' star Scarlett Johansson. Both would provide voices for the film's talking animals.

According to The Hollywood Reporter, Johansson would be voicing Kaa, the snake with hypnotic powers that it uses to stun its prey. She would then be the film's secondary villain, with the already cast Idris Elba playing the lead antagonist Shere Khan. Nyong'o would voice the mother wolf Rakcha, who adopts the main character Mowgli.

Considering this is voice work, it shouldn't change Nyong'o's chances of being in 'Star Wars: Episode 7,' which she's been rumored to be in talks to join. Nyong'o, who recently won the best supporting actress trophy for '12 Years a Slave,' has yet to sign on to her first big post-win role. While at this point Johansson seems like she's Favreau's lucky charm as this would be her third film with Favreau after 'Iron Man 2' and the upcoming 'Chef.' Johansson is currently shooting the highly anticipated 'The Avengers: Age of Ultron.'

Jon Favreau's 'The Jungle Book' is scheduled to hit theaters October 9, 2015, which is hopefully ahead of the Warner Brothers adaptation that Andy Serkis is attached to direct.
