The aim of the present study was to find out whether students' active involvement in classroom activities can promote language learning. This paper, using practitioner research, examines the active involvement of first-year engineering students in a film activity. The research took place in three phases: (1) the students were divided into five groups and given an assignment each, a month ahead, to edit a full-length movie to one hour without tampering with its story element; (2) the five groups presented five different edited movies on five different days; (3) the data was collected and analysed by the teacher as follows: observing the classroom performance, transcribing the students' spoken language, and collecting the students' written transcripts. The research analysis and discussion show that the whole process of the film task provided a rich input in listening and reading, and subsequently a productive language output in speaking and writing. The feedback conducted states that the students enjoyed the video classes thoroughly and the experience was rewarding because of their active involvement in the practice of LSRW skills.
