The only place I know to watch Little White Lie (in English) is through Netflix streaming or Comcast Xfinity (another streaming site) or through Starz (you have to pay to get the channel in order to watch it on tv or through the Starz website).

I don't think it will ever be available in English officially. I thought about starting a petition to RTE to get them to officially release it. I don't know how many people will be interested in signing it or how to go about making a petition and who to give it to.
