On Rick - it definitely took a while for me to get used to his accent. Andrew Lincoln is really well known for stuff over here in the UK.
Been lead characters is a few very popular series' - This Life which was iconic in the 90's and also Teachers from the 00's. He was also in a series called Strike BAck - not so iconic/poular/mainstream but I really liked it. And of course, he was in Love Actually.
I didn't remember him in
Love Actually, and of course I haven't seen those series.
I may have already said this and I'm not bothering to scroll back to check, but although I'm not that crazy about Rick's character, I saw Andrew Lincoln on TWD and found him charming and really funny.
Kelda, had you seen Maggie before? When she was on TWD, she had a British accent too. Seems like there's someone else on the show who also does, but I can't think who ....
