Once the trailer is over, make sure to lookout for the "You've earned your Farm Cash" phrase in the top right corner of the activity window, as more content is available for you after (like looking up showtimes and theaters for Cars 2) and you don't have to interact with any of it if you just wanted to grab your Farm Cash and run. Either way, make sure to complete these Farm Cash activity as soon as you spot it, as it likely won't be available for long, and you won't want to miss your chance at free Farm Cash!
