Well... that's a bit shorter than my dad, and my dad's a different generation, of course (born in 1944) - younger men tend to be taller. So, yeah, that would be below average for a guy of John Simm's generation, I think - but not dramatically so. So it seems to be a combination of *relative* shortness and tall co-stars. *g*

I'm always amused by that scene in 1.01 where Sam stumbles along the street, totally confused, bumping into people - and nearly all the people are women, and nearly all of them are taller than him. And him wearing cuban heels, too! *g*
