 "Ice" was also considered one of the best episodes of the first season by the production crew. According to Carter, Morgan and Wong "just outdid themselves on this show, as did director David Nutter, who really works so hard for us. I think they wrote a great script and he did a great job directing it, and we had a great supporting cast". Nutter said: "The real great thing about 'Ice' is that we were able to convey a strong sense of paranoia. It was also a great ensemble piece. We 're dealing with the most basic emotions of each character, ranging from their anger to their ignorance and fear. It established the emotional ties these two characters have with each other, which is very important. Scaring the hell out of the audience was definitely the key to the episode". Anderson said that "it was very intense. There was a lot of fear and paranoia going on. We had some great actors to work with".
