Robots 2: Ratchet Strikes Back

Robots: Ratchet Strikes Back is an American computer-animated science fiction adventure comedy film produced by 20th Century Animation and released by 20th Century Studios. It is the sequel to Robots (2005) and the second installment in the Robots film series. It was directed by Chris Wedge, written by David Lindsay-Abaire, Jonathan Aibel and Glenn Berger, and produced by William Joyce.

In the film’s ensemble voice cast, Ewan McGregor, Halle Berry, Greg Kinnear, Drew Carey, Amanda Bynes, Harland Williams, and Stanley Tucci reprised their roles from the first film. Robin Williams, who previously voiced Fender, died in August 2014, so his role was given to Ethan Trace; and Dianne West, who previously voiced Lydia, was replaced by Drew Barrymore due to West’s voice sounding way too old. The returning cast is joined by Laurence Fishburne, Emma Stone, and J.K. Simmons, who voiced new characters introduced in this film.

The computer animation for the film was provided by Reel FX Creative Studios, who had also provided animation for Ice Age: Freezing Finale.

This was Blue Sky Studios' second follow-up film outside of the Ice Age and Rio franchises.

Plot
Two years after the events of the first film, Rodney and Cappy get married at their wedding in Rivet Town and were always in the hopes of leaving town for their nice honeymoon. However, back in Robot City, Ratchet, who’s stuck in the ceiling with his father, plans to get revenge on Rodney and the gang for the death of his mother Madame Gasket. Meanwhile, Bigweld announces his retirement and appoints his brother Ironweld as the new leader of Bigweld Industries.
