funny enough i never watch the big bang theory but somehow by accident checking the sky channels i suddenly saw summer glaus name in the guest role for the terminator decoupling i really enjoyed seeing summer glau play her own part as a guest boy wasnt she so beautiful and charming sorry but i didnt watch anymore episodes of the big bang theory

I didn't watch the episode at all, i just watched the scene on the train in Youtube

I'm glad she guest starred in TBBT though because it gave Summer more exposure and the audience of TBBT is more sitcom than sci-fi (but maybe i'm wrong); which means it's helpul in the grand scheme of Summer Glau branching out from sci-fi.

As you may know, i'm a huge TSCC fan and i will always remember Summer Glau for her role as Cameron Phillips; that said, may i humbly remark that Summer played Cameron for two seasons in TSCC. That means she had time to dive deeper into the way she played Cameron and accompagny the character development, that's way more than she could do in Firefly, even if you take in account Serenity.

Of course Firefly has a greater impact on geek culture than TSCC but that doesn't necessarily mean that her "defining character" is River Tam.

your absolutely right chris spot on tscc will always be the best for summer glau for her role as cameron phillips and its a great shame as we all know it didnt get renewed for season three and enhance her reputation of what a great actress that she was as cameron phillips to me her defining character really should be cameron phillips but thats just my opinion as i love tscc as well

Here are links to two proposals made in jest, that i know of :
