President-elect Donald Trump's showbiz savvy is extending to his cabinet picks.

Portraying the future commander-in-chief as a casting director of sorts, the Washington Post suggested that Trump, the former star of The Apprentice reality show, is looking for 'the look' among his administration's nominees.

Those who don't have a certain physical presence are being dismissed, sources claimed, using former ambassador John Bolton and the walrus-like mustache attached to his face as an example.

'Donald was not going to like that mustache,' one associate told the newspaper. 'I can't think of anyone that's really close to Donald that has a beard that he likes.'

Bolton was among those Trump was looking at while shopping for a secretary of state.

He ended up choosing ExxonMobil CEO Rex Tillerson, who has no experience in government or politics, but a look – dark eyebrows and grey hair – that commands and says he means business.

Trump also contemplated the dashingly handsome Mitt Romney, despite the fact that the 2012 GOP nominee labeled the billionaire a 'phony' and a 'fraud' over the course of the campaign and actively worked against his nomination.

The Post suggested that South Carolina Gov. Nikki Haley, who endorsed Sens. Marco Rubio and Ted Cruz before saying she'd support Trump, was selected along the same lines.

Despite the fact that Haley has little diplomatic or foreign policy experience as a Southern governor, she'll be heading to the United Nations as an ambassador on behalf of Trump.

Going for her is an interesting immigrant backstory and she adds diversity to the cabinet, as both a woman and an Indian-American.

Trump's pick to lead the Department of Defense, retired Marine Gen. James 'Mad Dog' Mattis, has both a look – one that resembles General George Patton and the actor who played Patton in a 1970 biopic – and a nickname that Trump adores.

'You know he’s known as "Mad Dog" Mattis, right? "Mad Dog" for a reason,' Trump told the New York Times.

And Trump reportedly looked at a number of attractive women when looking for a press secretary, starting close to home with his campaign manager Kellyanne Conway.

Instead Conway accepted, as of this morning, the role of 'counselor to the president,' which means she'll work alongside the communications team, but not necessarily be a part of it.

Conservative talk show host and TV personality Laura Ingraham, along with Kimberly Guilfoyle and Monica Crowley, known to those who watch Fox News Channel, were also being considered.

The president-elect eventually settled on Sean Spicer, formerly the Republican National Committee's communications boss, as his loyal and pitbull-ish demeanor attracted the billionaire.

Trump's aides have reportedly come to terms with their overly visual boss, knowing that he'll knock off a candidate with a strong resume if that person doesn't fit the mold of what's in the president-elect's head.

'That's the language he speaks. He's very aesthetic,' a source told the Washington Post. 'You can come with somebody who is very much qualified for the job, but if they don't look the part, they're not going anywhere.'

While some have complained about Bolton being excluded from a high-profile government job because of his 'stache, including the social media-savvy American Mustache Institute, which called the move Trump's 'most offensive yet,' calling Trump out for his 'orange face and spaghetti squash mane.'

Bolton, today on Twitter, expressed confidence in his look.
