Former Australian Prime Minister John Howard has large bushy eyebrows which were frequently lampooned in political cartoons. Bob Hawke, two Prime Ministers ago, also partakes in the art of enormous eyebrows. Back in the day (40's to 60's), Prime Minister Robert Menzies also had these. Funnily enough, they are Australia's three longest serving Prime Ministers. Co-incidence? (Yes.)
As is British Chancellor of the Exchequer Alastair Darling- who has eyebrows and hair of different colours.
Darling is following in the footsteps of another British Labour Chancellor, Denis Healey, whose enormous bushy eyebrows were the subject of caricature on Spitting Image. Come to think of it, Conservative Chancellor Norman Lamont also had memetic eyebrows. Maybe it comes with the financial territory.
Let's not forget the famous Chinese warrior Guan Yu, whose eyebrows were 'thick as silkworms' ...Now, if only there was a trope for 'long and beautiful' beards.
One of Morrissey's most distinctive features, along with his chin and quiff haircut.
Daruma dolls often have big eyebrows painted on them (though they don't usually come with eyes painted on).
While hardly big by the standards of this page, Brooke Shields (especially in her early career◊) was known for her heavy eyebrows. Not bushy, but certainly more noticeable than most female movie stars.
Keira Knightley is sometimes mentioned in the same terms, but hers are hardly the same, despite one reviewer describing her as looking like "Natalie Portman in the early stages of a werewolf transformation".
Jenna Coleman treats her eyebrows, along with her large, expressive eyes, as a personal trademark. Early in her acting career, Coleman's eyebrows were noticably trimmed down for her role in Emmerdale, but she later stopped doing this. By Series 9 of Doctor Who, her eyebrows almost deserved co-star credit along with her eyes.
Maggie Thatcher's press secretary Sir Bernard Ingham. As those who watched Thatcher's funeral may have noticed, his already rather bushy eyebrows have become even more bushy with age, to the point where he now looks like he has pieces of cotton wool on his brow.
John Belushi had thick but very expressive eyebrows which helped make his performance as Bluto in Animal House a masterclass in silent comic acting.
Daniel Clark, who played Sean Cameron on Degrassi: The Next Generation, has some pretty thick eyebrows, which was lampshaded in the show at least once. His younger brother Robert, who's also an actor, has these as well.
