In the film, Frenzy is small, and very thin, standing at 1.2 m (around 4 feet) tall.[17] It is implied that he is also lightweight, given the ease with which a stewardess on Air Force One is able to pick him up while in his alternate mode. His alternate mode is shown as a silver GPX boombox, with round speakers and blue diode-lights.[18] At one point, he is decapitated and survives as just his head, scanning a mobile phone belonging to Mikaela to continue his task. His weapons include a small automatic weapon on each hand and CD-like shurikens that fire out of his chest. His character is manic (living up to his name), sometimes comedic, and he is the only Decepticon with blue colored optics, rather than the usual red.
Frenzy first appears when he infiltrates Air Force One to hack into the U.S. military's mainframe to find out Megatron's location. The military officials disrupt the downloads and send three secret service agents after the infiltrator, but Frenzy manages to kill them and escape. He then aids Barricade in locating Sam Witwicky. When let loose on Sam and Mikaela Banes, Frenzy attacks Sam but is decapitated by Mikaela using a reciprocating saw (a circular saw in the comic adaptation). He survives the injury and leaving his inert body behind, his head sprouts spider-like legs for movement, reformats into Mikaela's mobile phone and hides in her bag.
Later, he infiltrates the Hoover Dam and uses the power of the All Spark to regenerate his lost body. In the original script as well as the comic adaptation, he reattaches his original body, which is brought to him by the other Decepticons. He then proceeds to shut down the cooling systems, resulting in Megatron's reawakening, and alerts the Decepticons to the All Spark's presence. While attacking a group of humans in the control rooms, Frenzy accidentally kills himself when one of his own shurikens goes full circle and slices his head in two. He stumbles and falls to the floor presumably dead, ommiting the S word ("Oh ****" to be an exact quote).
He speaks mostly in Cybertronian, with occasional English words thrown in between, for example, when he frees Megatron from the hangar he speaks in Cybertronian with the English word 'Melting' used meaningfully "Megatron, Megatron.. MEGATRON!..ooh!...Megatron melting!" He also mutters constantly in Cybertronian and makes noises that sound like English words (even swear words at one point) He also makes a obscene hand gesture at the humans who were standing near Barricade. He also makes groaning and creaking sounds even when he is just walking, these sounds are cartoonish in nature, For example, before hacking the computer in Air force One he 'cracks' his knuckles, as if in preparation
