<P> Ben also appears to know Turkish, as he asks the bedouins on horseback "Türkçe biliyor musunuz?" late in season 4 . </P> <P> In 2001, Michael Emerson won a Primetime Emmy Award for his guest appearance as serial killer William Hinks on The Practice . The Lost producers liked his work on The Practice, so they were keen to cast Emerson in the role of Ben, then known as "Henry Gale", as they thought he would fit the character well . He was originally contracted to appear in just three episodes of Lost, making his first appearance midway through the second season, in episode "One of Them". The producers were so impressed by him that they contracted him for a further five episodes, citing the scene at the end of "The Whole Truth" where Ben asks for milk as the moment they knew he was a "keeper". He was then made a part of the regular cast from the third season . Had Emerson not worked out during his initial appearances a different actor would have been cast for the leader of the Others, but it was always intended the survivors would have the leader right under their noses and not realize it . During one episode of the Official Lost Podcast, the producers state they always knew Ben would be the "Big Bad". Emerson had no idea of his character's importance during his second season recurring role . He was told nothing about Ben's backstory and would only receive scripts at the last minute . He enjoyed how the ambiguity of Ben's motives allowed him to "paint it the way (he) please (s)". Sterling Beaumon was cast to play Ben in the flashbacks of episode "The Man Behind the Curtain". Emerson's wife Carrie Preston was cast as Ben's mother following Emerson telling people at parties she was desperate for a part on the show . </P> <P> Referring to the scene in the third season where Ben seemingly fits Sawyer with a lethal pacemaker, Emerson comments "Sadistic may be the word, but he doesn't seem to take much relish in it . He's just sort of detached, he looks at it coldly . I sometimes feel like everything to him is a sort of scientific experiment and he is interested in a dispassionate way in how the experiment runs its course . I think some day if we ever find out what his parentage is, that his parents were people of science". Elizabeth Mitchell, who plays Juliet, did not think it was a "huge surprise for Juliet that Ben had feelings for (Juliet), but I still think it was...it was horrifying under the circumstances". She also thought "(Juliet has) this kind of wonderful mind, and I think that Ben probably has a tremendous respect for that . It's not because Juliet is so enticing, it's just the fact that she's got this amazing mind, she has this amazing, you know, intelligence, and I think that's what intrigues him, that's what draws him into her". During season four the producers deliberately left it ambiguous as to whether Ben was a part of the Oceanic 6 (six survivors of the plane crash that make it off the Island) after he appeared in one of Sayid's flashforwards . </P> <P> During the beginning of season three, Chris Carabott from IGN described Ben as "one of the best' villains on television', due to his' eerie manner' and' methodical delivery"'. Later in the season Carabott had a problem with Ben being so deceptive, as "anything he imparts must be taken with a grain of salt". Jeff Jensen of Entertainment Weekly also noted this, saying "I don't trust Ben . I have no idea when he's lying and when he's telling the truth . The only thing I'm reasonably sure of is that everything he says is for the purpose of impacting a character--and the audience". Ben's father issues revealed towards the end of season three are described as "not the most original Lost character trait by any means but it is the thrust behind Ben's development into the genocidal maniac he eventually becomes". Following the penultimate episode of the season, Carabott stated "Even with his limited screen time, Michael Emerson's performance shines through and we hope that he survives the events of the finale because we love seeing his character every week ." Erin Martell from TV Squad picked the Others as one of her season three highlights, partly due to the development of Ben, adding "I cannot even picture the final three seasons without Ben". Martell also gave six reasons to look forward to season four, one of which was Ben Linus . </P>
