Can you guess who this female actor with old man make up is?

You think you are a Hollywood know-it-all? You think you know all the biggest stars? Well, here is a test to test your faith in yourself.

Below is a picture of a female actor shooting for her upcoming film. The catch here is that the make-up and costume make her look nothing like her real self.

Any idea?

We can tell you she is a known master of disguise.

OK fine, we’ll reveal it to you....

*Drum roll *

It’s Tilda Swinton!

The British actor is currently shooting for the remake of 1977 Italian triller, Suspiria. But as to why has she donned the elderly man make up is still a mystery.

Tilda has previously also experimented with different looks for her films. Here she is in The Chronicles of Narnia: The Lion, the Witch and the Wardrobe playing the White Witch.

In Trainwreck

In The Grand Budapest Hotel

In Snowpiercer

And in her last film, Doctor Strange

Suspiria is about a newcomer to a fancy ballet academy who gradually realises that the school is a front for something far more sinister and supernatural because of a series of grisly murders. It also stars Fifty Shades of Grey’s Dakota Johnson and Kick-Ass’s Chloe Grace Moretz.
