Wish he had kept his real accent on The 100!
Such a shame that they made him put on an American accent in The 100. He couldn't even pull it off very well. His Scottish accent is so heavy, it was obviously difficult to keep the American thing up.
BUT giving him his native accent would've not only made him more comfortable to play the character, it would also add a bit more of an international feel to the ark. It seems a bit weird that everyone is American, even though during season 1 they allude to the fact that a whole bunch of different countries came together to contribute to the final ark.
I dunno, I guess I just think it would make his character so much more interesting with his native accent. He should've pushed for it a lot more. Was so good to see it work in LOST. It really could've worked here too.
