Love him or loathe him, there's no denying that Tom Cruise basically stole Tropic Thunder. While the movie was filled with controversy, such as Robert Downey Jr.'s character's acting choices, the 2008 film remains beloved. In the film, Tom Cruise played a vile Hollywood mogul named Les Grossman. Given Tom's incredible filmography, it makes sense that he brought this character to life so well. But given Tom's recent set outburst as well as his not-so-clean reputation among some in Hollywood perhaps his casting was even more calculated. Either way, Tom Cruise absolutely knocked this role out of the park. Thanks to a fantastic article by Grantland, we now know how he was able to do this...

Tom Was Supposed To Play Ben's Role Until He Gave A Very Specific Script Note

Tom Cruise needed to repair his image in 2007. Years of conflict with marriages, jumping on couches, and squabbles with the studio making his Mission Impossible movies put him in a bad light. Ultimately, Tropic Thunder was the film that helped (momentarily) rehabilitate his image. But Tom wasn't supposed to play Les Grossman, the vicious studio executive who clearly believed actors were disposable. Actually, Tom was supposed to play the leading role that Ben Stiller ended up taking. It made sense that Ben wasn't initially interested in the lead role. After all, he was already directing it and writing it with Justin Theroux and Etan Cohen.

"Justin Theroux and I had been working on the script on and off for eight years," Ben Stiller said to Grantland. "We had an outline and about half a script. I knew how it should end. Then we brought Etan on and got a full draft."

When Etan Cohen came on in 2002, he basically came up with the idea that would lead Tom Cruise to essentially create Les Grossman.

"We were still figuring out why the actors would get abandoned and no one would notice that all these stars were gone," Etan Cohen said. "So I had written this throwaway thing at the side of the document that said: 'Maybe the studio has an insurance policy on production. When the director dies they recoup all their expenses, so the studio doesn’t care about the actors.' Then we totally went away from that for years."

By that time, Tom Cruise had already read the script and claimed that there was a need for another villain. In fact, he even stated that it could use a greedy studio exec who 'represents the gross part of Hollywood'.

"His idea to show the studio head actually fixed a problem we had for a long time. We never cut back to the real world for any of the previous drafts. All the Grossman scenes totally fixed the plot holes" Ben Stiller claimed.

Soon after, a new draft was written and Ben gave the role of the studio exec to Tom, who couldn't take it due to scheduling conflicts. But there was no name for the character at first. In fact, it took an entire year for 'Les Grossman' to officially be created.

"Ben decided he was going to play Speedman, and then he got a phone call from Tom, who said he just couldn’t get the script out of his mind. Tom asked, 'What else is open?' And Ben said, 'Well, we haven’t cast the Les Grossman role yet.' Tom was like, 'I’d play that,'" producer Stuart Cornfeld said.

Les Grossman's Look Was Half The Performance

While Tom brought a certain amount of energy to the role, his hair, make-up, and prosthetics were really what made the performance memorable. After all, Tom was barely recognizable.

"I was Tom’s go-to makeup person from Interview With the Vampire on. I did a lot of big, iconic looks for him," makeup designer Michèle Burke said. "I got a text saying, 'Tom wants to have hairy arms.' And I was thinking, Oh, OK, we can get hairy arms. Then they were like, 'We want him to have a hairy chest.' Then suddenly it was like he’s going to have big hands, and I’m sitting there thinking, This is getting bigger than I expected. Then they started sending me pictures of other people who looked a bit like this. You know, with the gold jewelry, the hairy chest. I thought, OK, now I’m beginning to get the picture, this is full-on."

Then, of course, there was the fat suit which was a bunch of custom pads made out of foam and beading from the inside of a pillow. This beading accurately mimicked the jiggle that human fat makes when it moves; something that was vital for the dance number...

All About Tom Cruise Dancing

"We’re doing the makeup test and it’s the first time Tom’s in the Les Grossman outfit. He stops and says, 'Maybe I should dance in this. You know, I haven’t danced in a movie in a long time,'" producer Stuart Cornfeld said.

The Mission Impossible and Eye Wide Shut star ended up choreographing all of his own dance moves which just made everyone on the set burst out laughing.

"I remember him standing off in a corner just working on his moves," co-star Bill Hader explained.

The outrageous costume, hair, and make-up, the hilarious lines (mostly written by Justin Theroux), as well as the performance and energy that Tom Cruise brought to the role, ended up creating a truly memorable character.
