Star Chris Pratt admits that physically,Jurassic World: Fallen Kingdomwas a much harder shoot.

We upped the stunt game, he says.

I just got banged up more on this one.

The shoot required about a week in a huge water tank.

It was tough, Pratt recalls.

I had to see how long I could hold my breath, like underwater.

I only got about a minute at a time.

Thats pretty good, but I think Tom Cruise can do like 20 minutes or something like that.

But then things got even tougher.

It ruined my hair, Pratt says.

My eyes got so bloodshot-red.

Just to be clear, thats your urine in my eyeballs?
