At the risk of diving into the annoying and frankly nonsensical discourse surrounding nepotism in the film industry, Amy Redford’s sophomore feature “What Comes Around” represents a curious object. Directed by Robert Redford’s daughter, starring Joaquin Phoenix’s sister Summer Phoenix and Casper Van Dien’s daughter Grace Van Dien (not to mention a cameo appearance by Phoenix and Casey Affleck’s son Indiana), this little IFC Films thriller has more than enough tangential associations.
