This article is based on findings arising from a large, two-year EU project entitled "Creating Machinima to Enhance Online Language Learning and Teaching" (CAMELOT), which was the first to investigate the potential of machinima, a form of virtual filmmaking that uses screen captures to record activity in immersive 3D environments, for language teaching. The article examines interaction in two particular phases of the project: facilitator-novice teacher interaction in an online teacher training course which took place in Second Life and teachers' field-testing of machinima which arose from it. Examining qualitative data from interviews and screen recordings following two iterations of a 6-week online teacher training course which was designed to train novice teachers how to produce machinima and the evaluation of the field-testing, the article highlights the pitfalls teachers encountered and reinforces the argument that creating opportunities for pedagogical purposes in virtual worlds implies that teachers need to change their perspectives to take advantage of the affordances offered.
