Jimmy

In the original film Jimmy play a minor part, his name only being mentioned a few times. He carried the smoke grenades which helped the sailors. He was most likely killed during the log scene. In the 2005 remake he's the lookout of the Venture and a close friend with first mate Ben Hayes who he views as a father figure. He is much younger and something of a kleptomaniac, introduced stealing Jack Driscoll's pen when he brings him his lunch. After making Jimmy return the pen and chasing him off, Hayes tells Driscoll that Jimmy doesn't mean any harm, and informs him that he found him hiding in a cage some years ago, with his arm broken in two places, and "wilder than half the animals in here." Hayes says, further, "He still won't tell me where he came from, but it wasn't any place good." He is shown to vandalized Bruce Baxter's posters as he comes out, Bruce spots him, he hides the pen then acts natural, not before putting on a smile. Then he was eavedropping on Carl Denham and Jack speaking where they were acutally headed to Skull Island, not Singapore. Then he starts telling Hayes and some of the crewman(Venture Crewman 4, Venture Crewman 22,Venture Crewman 27).

When Hayes takes some men with him to find Ann, Jimmy attempts to sneak in by disguising himself using a ski cap. Hayes sees through Jimmy's disguise, but after being convinced, allows Jimmy to stay. As they face King Kong, Hayes attempts to take on King Kong to allow his men to escape, and specifically tells Jimmy to run. Jimmy can only watch and cry out in horror as he watches the monstorous ape kill his father like figure as King Kong throws Hayes against a cliff wall. He then hangs on for dear life to the tree trunk as Kong sends the rest of the men down a ravine.

Jimmy surivives the fall, and breaks down over Hayes death and embraces Jack. When the survivors are attacked by oversized insects, Jimmy saves Jack's life by shooting wildly at some insects that were attempting to strangle him. He was on of the three survivors left (the others being Jack and Carl) when they are finally rescued by Captain Englehorn.

In the scene where Kong tries to recapture Ann Darrow, Jimmy shoots at Kong with a Tommy gun but is injured when Kong throws his boat against a boulder. He is badly injured and is last seen being held above the water by Jack, knocked out. He likely returns to America with the others.

He appears in the video game, but he is not able to use guns, despite using them in the movie, and is show using a pistol in a scene before becoming a ally.
