We’ve learned of a rumor (via Hollywood Reporter) that claims a big budget, live-action Pokemon movie is in the works.

According to the source, a top-secret auction for or film rights to the Pokemon franchise is nearly done, with Thomas Tull’s Legendary Entertainment brushing aside the previous potential studio, Warner Bros., with Sony following as another very interested party. Warner Bros., Sony, and Legendary declined to comment.

Despite the interest of Sony and Warner Bros., the source claims Legendary is the most likely candidate in the auction of the movie license.
