Whoa, whoa, whoa! I didn't know Dan Aykroyd was in this picture!
~ Mr. Swackhammer

Mr. Swackhammer is the main antagonist of the 1996 Warner Bros. hybrid film, Space Jam. He is the evil alien owner of the intergalactic amusement park, Moron Mountain, who seeks to enslave and bring the Looney Tunes cast to his park in order to attract more customers.

He was voiced by the famous actor, Danny DeVito, who also portrayed The Penguin from Batman Returns, and Mr. Harry Wormwood from Matilda.


In Space Jam

Although he is the main antagonist, his role in the film is small. Mr. Swackhammer is the evil alien owner of Moron Mountain who realizes that no one is returning to Moron Mountain and that his business is failing. He decides to send the Nerdlucks to capture the Looney Tunes to perform their comedic acts in his amusement park, hoping that it could bring back customers as his newest attractions and save his business from foreclosure. This results in a basketball game and Mr. Swackhammer later comes to Earth to watch the Monstars and the Looney Tunes play basketball as the Monstars coach.

Michael Jordan makes a deal with him that if the Monstars win, Mr. Swackhammer would spare the Looney Tunes in exchange for his own freedom as his newest attraction in Moron Mountain. He readily accepts it, thinking of the conceivable possibilities of Jordan as his newest attraction, playing basketball with his customers while chained up meaning he would always lose no matter what he did.

However, the Monstars lost to the Looney Tunes, resulting in Mr. Swackhammer being furious and berating the Monstars for failing. The Monstars told Michael Jordan that they were afraid of Mr. Swackhammer because he was bigger than them, although they realize their current forms are far bigger and more powerful than he is. Because of this, the Monstars turn on Mr. Swackhammer and strap him to a rocket sending him straight to the moon and possibly back to Moron Mountain. Swackhammer and Moron Mountain presumably went out of business following his defeat.


Mr. Swackhammer is known for being extremely short-tempered, argumentative, sarcastic, and overall evil in nature. He is a greedy and manipulative businessman who formerly enslaves the Looney Tunes as his new workers of Moron Mountain He is very vituperative, opprobrious, abusive, and nasty to the Nerdlucks. One of his most contemptible and outrageous plans is when he makes the Monstars win the basketball game by any means necessary.
