In this ESL lesson plan for adults and teens, students watch a trailer and do a listening exercise for the new 'Joker' film coming out in October 2019. It includes discussion questions and conversation activities about Batman, the Joker, and villains. Students also learn some important vocabulary terms and phrases from the trailer. The grammar exercise features subject + used to + verb. There is also a fun 'Interview' section, a quiz & review, and a bonus writing activity.
