The Smurfs 3

By May 10, 2012, just two weeks after production of The Smurfs 2 was announced, Sony Pictures Animation and Columbia Pictures had been already developing a script for The Smurfs 3, with writers Karey Kirkpatrick and Chris Poche.[3] Hank Azaria, who played the live-action Gargamel, said that the third film "might actually deal with the genuine origin of how all these characters ran into each other way back when."[4] In March 2014, Sony announced that it will reboot the series with a completely computer-animated film.[5]
