Gill Hammerstein is a hammerhead shark who is the executive producer of Mermaid Man and Barnacle Boy: The Movie in the video game Lights, Camera, Pants! He is voiced by Nolan North.
He is a hammerhead shark and wears khaki pants with a belt. He also has a red collared shirt, and wears a pair of brown shoes (black in the console versions). In the console versions, he wears a pair of glasses.
In the console version, he was quite nice and funny since Gill has the funny moments. In the PC version, he seems neutral, and sometimes nasty because he shouts a lot. He is a depiction of a loud, fast and usually realistic TV producer.
"Go back to acting school!"
"Go out there and do better!"
"What was that? Was that acting? I don't think so. Try again!"
"Ms. Peddington, get me the first contest host on the line! NOW!"
"Terrible... just terrible! Go back and do better!"
"UHH!! Now I'm upset!!!"
His voice is similar to Sid from Ice Age in the console version.
