Ubisoft Motion Pictures CEO Jean-Julien Baronnet is optimistic about Tom Hardy getting the role. In an interview with Collider, she says:
“Tom Hardy is currently one of the biggest talents in the film industry, and he has a phenomenal ability to take on complex and varied roles with his broad range of acting skills. His involvement in the ‘Tom Clancy’s Splinter Cell’ movie is exciting news for movie and video game fans alike. Meanwhile, Eric Singer is one of the most talented writers of the moment, and … we’re confident he’ll bring a fresh approach and create a thrilling story … while still respecting all the codes and traditions of the franchise that are so important to fans.”
If you ask me, I'd rather have Paramount acquire this movie, so that they could possibly, somehow, play with the idea of Sam Fisher (Splinter Cell's main protagonist) or any other character establish some possible interaction with the other Tom Clancy movie adaptations that Paramount is producing. Something which is not a necessity anyway, since in the books (and in the game), Sam Fisher doesnt interact with Jack Ryan characters anyway. Paramount is set to release the Jack Ryan reboot December this year, with Chris Pine, Kiera Knightley, Kevin Costner, and Kenneth Branagh also as director. The Jack Ryan series of books were written by Clancy. And then there's also an adaptation of Clancy's novel "Without Remorse" which is currently in development, and wherein Tom Hardy is also been tapped to play.
There has been no official word as of yet as to which role Hardy will be taking. I'd rather see him in "Without Remorse" because it requires a more dramatic approach than "Splinter cell" which might be more focused merely on the action, especially because the movie adaptation will be based off the games rather than the Tom Clancy novels that inspired the series.
