Smallville, small problems

Jon and I have been enjoying Smallville during these dark, cold wintery days.

Some observations:
1) All the 'teenagers' are clearly being played by people in their mid twenties, and furthermore one of them in particular sports rather pronounced laughter lines. Now, even if you insist on playing [American] football every day, is the sun really so strong in that particular town in Kansas to cause such bad premature ageing?
2) Spot the cameos/extras/pre-fame actors. Ones of note? Evangeline Lilly in the background at a party, Adam Brody being typically, well, angst-y.

In addition, Jon and I have started a new game entitled 'Stuff Clark Needs'. So far we'd recommend he gets hold of a cellphone and an umbrella...
