I swear I saw him in London on Friday

In Leicester Square. At first when I saw him I kept thinking how much he resembled a young Clark Kent (Reeves), especially since he also had glasses on. Then after a closer inspection, I realised he looked exactly like Walt Jr. I have a sharp eye and it's unlikely I could mistake anyone for Mitte (given his unique featues) He looked tall, about 6'1" (which correlates with his IMDb listing).

I'm actually certain it was him. He was with a female companian dark hair. I'm not if she was a relation or his girlfriend
