Dwayne King is the main antagonist of the comedy-action film 30 Minutes or Less.  He is played by Danny McBride.

Nick (Jesse Eisenberg) is a slacking, marijuana fuelled pizza delivery driver who has trouble completing the "30 Minutes Or Less" policy that his employer issues, leading to a reprimand from his boss Chris (Brett Gelman). Nick's friend Chet (Aziz Ansari), a school teacher, discovers that Nick has slept with & still has feelings for, Chet's twin sister Kate (Dilshad Vadsaria). It is also revealed that Chet was the reason Nick's parents divorced, because he told Nick's father that his wife had been cheating on him with a lifeguard. After a heated argument, the 2 end their friendship.

Meanwhile, 2 delinquents named Dwayne King & Travis Cord (Danny McBride & Nick Swardson) are miserable living under the shadow of Dwayne's domineering father the Major (Fred Ward). Dwayne confides in stripper Juicy (Bianca Kajlich) about his contempt for his dad, who is squandering the money that he won playing the lottery. Juicy says she can hire a hitman to kill Dwayne's dad for $100,000 so Dwayne can collect the inheritance. Dwayne plots that they kidnap a complete stranger & force him to rob a bank for the hit money by strapping a bomb to his chest. After seeing an advertisement for the pizzeria that Nick works at, they order a pizza & wait for a driver to come to their hideout. When Nick arrives, Dwayne & Travis (who are wearing a gorilla & monkey mask) assault him & knock him unconscious.

When Nick wakes up, he finds a vest rigged with explosives strapped & buckled onto his torso. Dwayne & Travis tell him his situation: if he does not rob a bank in 10 hours, they will detonate the bomb, demonstrating the bomb on a stuffed Teddy bear. Dwayne states that if he dares to go to the police, they will detonate the bomb as they will be monitoring him & they end up sending Nick on his way. In his panic, Nick goes to a school where Chet is working & desperately pleads with him to help. After plans to deactivate or remove the bomb are dashed, Chet says he has no choice but to rob the bank. Still uneasy, Nick asks Chet to assist him. Chet reluctantly agrees.

After purchasing airsoft guns, spray paint, 5-Hour Energy & ski masks for the robbery, Nick suggests stealing Chet's family friend's Datsun 280ZX so that the police will be unable to track the license plate number of Nick's Mustang. Nick then stops by his workplace to tell off his boss & to go see Kate & say some final words to her. Nick & Chet later arrive at the bank, hold it up & obtain the money upon forcing a bank employee named Sandra (Rebecca Cox) to empty the vault. Though one bag of money was rigged with dye, Chet forces Sandra to get the ones that are not rigged with dye. However, the bank manager had pulled the alarm, forcing Nick & Chet to flee as Dwayne & Travis watch. After a car chase that ends up with Nick & Chet crashing the 280ZX, the 2 successfully evade capture by sneaking onto a bus. Nick calls Dwayne & tells him he has the money. Dwayne says he & Travis will meet him at an abandoned rail-yard to make the exchange. Dwayne & Travis go to a restaurant instead. When Dwayne asks Travis to possibly be the one to detonate the bomb if the time comes, Travis starts to become unsettled.

After getting his Mustang, Nick waits for Dwayne & Travis at the railyard while Chet hides somewhere to avoid a confrontation about his involvement in the scheme. Instead of Dwayne or Travis however, Juicy & the hitman Chongo (Michael Peña) are the ones who arrive to pick up the money. Nick hands Chongo the money & expects Chongo to give him the code which will deactivate the bomb. Chongo claims he doesn't know what the code is. When Nick keeps asking him for the code, Chongo gets aggravated & holds Nick at gunpoint. Chet runs in & beats Chongo while Nick incapacitates Juicy. The 2 grab the money & escape.

Dwayne ends up getting 2 phone calls: one from Chongo calling to let Dwayne know that because of Chet's ambush, he will be coming after Dwayne also. The second is from Nick who berates Dwayne for not giving Chongo the code to the bomb & dares him to detonate the bomb with the money at his side. Overly frustrated by these turn of events, Dwayne activates the speed dial number on his phone for the bomb to explode, but finds that Travis altered the numbers while Dwayne wasn't looking because he was getting nervous about Dwayne's gradually violent attitude. The 2 head back to Kate's apartment in their masks & kidnap her from the girls' bathroom. Dwayne calls Nick to let him know that he has Kate & if he doesn't meet at the scrapyard to give him the money, he will kill her. Meanwhile, Chongo breaks into the Major's house to find information regarding Dwayne's location & finds a hand-drawn map to the scrapyard. While there, the Major attacks him with a pen gun & is shot in the stomach after a struggle.

Nick arrives at the scrapyard & exchanges the money for Kate. Dwayne gives Nick the code (which is 69 69 69) to deactivate & unbuckle the bomb with minutes to spare. Dwayne then tells Nick to walk away, but Nick deduces that as soon as Nick & Kate turn around, they will just kill them both. Dwayne confirms this by pointing a gun at them while Travis comes out wielding a flamethrower. Nick says he hired a sniper in case this were to happen. This is proved to be fake as it is only Chet who is using a laser pointer, but it is enough to fool Dwayne & Travis into lowering their weapons. Chongo arrives shortly after & knocks Nick out cold, then spots Dwayne & Travis. Despite handing him the money, Chongo holds the 2 at gun point. Pressured, Travis responds by torching Chongo with the flamethrower. Although burnt to death, Chongo manages to shoot Dwayne in the shoulder & shoot the fuel tank for the flamethrower causing it to explode on Travis's back. Nick quickly wakes up, grabs the money & drives away with Chet & Kate. Still alive, Dwayne spots them running off, but first reconciles with Travis upon putting out the flames on him before heading off. Dwayne catches up to the others with his van, but he hears a beeping sound in the back & the van explodes. Nick reveals that as he grabbed the money, he reactivated the bomb & threw it in the back of the van.
