He has plenty of credit prior to GoT, but I don't recall ever seeing him before.

The only actors I recognized from the GOT pilot episode were Lena Headey, Sean Bean and Jason Momoa. Everyone else was a total unknown to me.

Later on I found out that Peter Dinklage had done a few things before GOT but I didn't watch any of them.
