But, Markazia is in Polaris, while the movie takes place in Solana. That's just too far, unless she is quite like Ratchet, sent to Solana for safety reasons.
Oh really, then explain how did Tharpods and Fongoids get there. Were those green little creatures from QfB's caves "sent to Solana for safety reasons" as well? They're just using as many assets from the existing games as possible and making the designs from PS3 games look good in the movie didn't require nearly as much work as with the ones from the PS2 days. And so, they're using them, there's not much more to it. It's a new canon, why can't they make all the creatures of Polaris live in Solana now? I wouldn't be suprised if we got to see some Terachnoids or Fongoids in the movie as well. It's not like they gave Ratchet parents or a (completely unnecessary in the duo's origins story) love inte… Oh… *censored* 
Just checking the Cannes movies of this year… I can't see the RaC movie anywhere.
It wasn't on the main festival, those were screenings just for interested distributors. You know, they still have to close deals in some countries…
