I said to his rehabber, Hesobviouslya male, she remembers with a laugh.

Thats not fair to call him Sally.

She knew he was male but she just liked to call him Sally.

All of them stayed in aviaries set up in the studio, with pools to help them learn.

He was intrigued by the whole thing, she says.

As a bird, he was very curious, and curious animals are easy to train.

It was like training a dog, she says.

Our goal was we wanted them to have fun, to see to it they werent scared.

And whats more fun than getting treats?

Im sure there are some amazing outtakes between the two of them.

Becoming Sullys source for food made Lively an instant Sully magnet.

He ended up nuzzling next to her and one day he started pecking at her fake shark bite.

Improvised moments like those made Sully stand out, she adds.

He offered up a lot of stuff and she went with it, which was terrific.

They had a bit of a rapport which was really nice.

(In the script, the seagull was named Sid, a shoutout to Sid and Nancy.)

She laughs, remembering the tough shoot.

Finally, after trying again for the shot the next morning, Sully stayed.

A Big Splash

Over the course of the shoot, Sully becameThe Shallows mascot.

Everybody loved him, to be totally honest, Brock-Medland says.

Blake once turned around to me and said, I think Im being out-acted by your bird.

Good thing both actors, human and avian, toughed it out.

Sully was a trooper.

And with the grueling role under his proverbial belt, Sully seems primed for stardom.

If there isnt another role for him, hes going to end on a high, she says.

Hes done his best.
