Bruce Willis has range — and so does his dome.

The "Die Hard" actor stopped by Jimmy Fallon's "Tonight Show" on Friday with a beautifully coiffed crop of perfectly blond Donald Trump hair — not his usual shaved-bald look.

"It suddenly it's just seemed to grow exponentially … I was a blond when I was a kid," Willis told Fallon, assuring his NBC host that the obviously mocking wig was his real hair. Sound familiar?

Fallon then took the site gag a bit further, sharing photos of Willis from some of his most famous films, photoshopped with unruly Trump hair. The "Tonight Show" gang even managed to superimpose the GOP frontrunner's hair on Willis in a "Sixth Sense" clip.

In a second segment last night, Willis donned a red "Make America Great Again" cap, also a la the "Celebrity Apprentice" host-turned presidential candidate.

The movie star was on the couch promoting new film "Rock the Casbah" with Bill Murray, which comes out on Friday.
