Even if you don’t know the Kasdan family, you undoubtedly know their work. New Hollywood titan Lawrence Kasdan wrote the screenplays for EMPIRE STRIKES BACK and RAIDERS OF THE LOST ARK. In the last 15 years, his sons Jake and Jon have taken up the family trade. This week, we watch their first major films to develop a theory of the family. To start, BODY HEAT (1981) is an early and electric take on the erotic thriller with two ’80s stars in their primes. At 20:20, ORANGE COUNTY (2002) has slapstick energy, but what else? At 30:37, we conclude with IN THE LAND OF WOMEN (2007), a movie that’s a little painful for Noah to reappraise.
