Harry Potter and Doctor Who fans are definitely two groups of people that are dedicated to their Sci-Fi, fantasy franchises, but what if the two worlds collided? Well, that could be the case since actor Matt Smith, who portrayed the 11^th regeneration of The Doctor on the BBC series is the subject of casting rumors for the upcoming Potter spin-off movie project, Fantastic Beasts and Where to Find Them. Also penned by author J.K. Rowling, this new project is set as a stand-alone story within the universe of the Potter stories, but with a whole new adventure. We'll have to wait and see if this casting speculation is true, but fans have already started a petition to get Smith singed on for the leading role, Newt Scamander!

Director David Yates has signed on to helm the project, which is fitting since he directed the final four Harry Potter movies, but no casting news has been reported until this week with Smith. According to The Sun (via MTV News), Smith is the "favorite" to lead the project, which definitely has fans excited!

A petition has already been drafted on Change.org, suggesting Smith would be a great actor to portray the lead, Scamander. Though the scribes of the petition admit that not much is known about this main character, the knowledge of the Potter universe and Smith's talents as an actor have fans certain he's the right choice! You can check out this petition right here!

It's true; we really don't know much about this project. According to IGN, though, producer David Heyman described Rowling's script as "sublime," stating: "It's funny, it's vivid, it's exciting. It's filled with all the hallmarks of [Rowling's] incredible imagination."
