Morgan Freeman is in final talks to star in Luc Besson's action-thriller Lucy.
The Dark Knight star is said to be "in final negotiations" to join Scarlett Johansson in the upcoming film, reported The Wrap.
The Avengers actress is already on board to play the title character - a reluctant drug mule, who is transformed into an incredible fighter when one of the drugs enters her system. But despite gaining special powers of clairvoyance, telekinesis and the ability to ignore pain and emotion, she faces a race against time to survive.
Morgan is tipped for the role of "a professor well-versed in evolution and the capabilities of the human brain", who Scarlett's character is on the mission to find before she loses her fight for life.
The Oscar-winning actor - who was last seen in Joseph Kosinski's sci-fi epic Oblivion opposite Tom Cruise and action thriller Olympus Has Fallen - will next appear in magic movie Now You See Me alongside Jesse Eisenberg and Isla Fisher.
The 76-year-old is also attached to road trip comedy Last Vegas with Michael Douglas and Robert De Niro, action film The Last Knights with Clive Owen, Wally Pfister's Transcendence and The Lego Movie.
Scarlett, who previously appeared in Hitchcock opposite Dame Helen Mirren and Sir Anthony Hopkins, will next star in Joseph Gordon-Levitt's directorial debut Don Jon and Spike Jonze's sci-fi drama Her.
She's also set to reprise her role as the Black Widow in Captain America: The Winter Soldier and the upcoming Avengers sequel, as well as starring in Jonathan Glazer's big-screen adaptation of Michel Faber's novel Under The Skin.
