LONDON -- The sex video with horny womenBritish actor Henry Cavill is a large man who clearly spends time at the gym, but -- despite what his on-screen persona might suggest -- he does not possess super-human strength.

Instagram users didn't know quite what to make of it.

Some people were impressed.

Others were confused.

Eventually, though, some people spotted a clue.

The optical illusion becomes clear if you look at the shadows behind him.

As strong as Cavill undoubtedly is, he was being assisted in the picture by a powerful, mechanical ally.

The crane is also just about visible at the very top of the picture, too.

We see you, Cavill.
