Below is the said trailer:
After watching the trailer for the first time, I think this looks like a fun little animated movie. It looks like its staying true to its source material, the animation looks great and we get to see a few glimpses of the weapons and gadgets that many Ratchet and Clank fans will recognize. I am still a bit worried for the film because the animation studio (Rainmaker) doesn't have a good track record, mainly making Barbie straight to video movies and Escape from Planet Earth, which wasn't well received. But I have my fingers crossed hoping that this film can break the wretched video game to movie adaptation curse and be decent.
It certainly has the tools to do so like having TJ Fixman (no pun intended) as the writer of the film. Fixman has been a writer for the Ratchet and Clank games since Tools of Destruction. Also, the games' voices for Ratchet, Clank, Qwark and Dr. Nefarious (try to spot him in the trailer), will all reprise their roles. Though some celebrities are in to lend their voices too, like Paul Giamatti voicing Chairman Drek, the main villain from the first game.
I don't know, looks better than The Angry Birds Movie, which releases three weeks after Ratchet and Clank.
