Why is his profile photo opening a water bottle?

Because it looks better than opening a beer bottle.

He was thirsty...

It appears my hypocrisy knows no bounds.

I think it was taken one year at the BAFTAs.

To show that Tom Hardy can look sexy doing anything.. even opening water bottles.

Good question.

Answer: because he can pull it off. Wouldn’t you say so? The pic is self-explanatory. In short, Tom f’n Hardy! :D

Slick bloke.

Maybe he was submitting a urine sample and reflecting on the many implications of it.

He's trying to piss off Aquaman.
