2nd weekend derivatives. Not for every movie obviously but there are so many weekends after big movies with smaller movies that might not necessarily get derivatives, so for like a movie like Captain America, a 2nd weekend derivative might be interesting, because we wouldn't even have previews to go by if they halt on Friday. Of course, they'd probably have to be offered on the calendar at a reasonable price after a movie's opening weekend (so maybe Tuesday?) So like say Captain America opens with $120 million, maybe the 2nd weekend derivative would be priced at H$50 to H$60 and the players have to decide how frontloaded the movie might be. Since they're behave like normal OW derivatives (in terms of halt and delist), it shouldn't be hard to give it a try.
