‘This Is My Life’

Director/co-writer Nora Ephron’s smart and likable adaptation of Meg Wolitzer’s tale of a stand-up comedian and her two daughters--originally called “This Is Your Life”--is a bit too thin and perfunctory when it looks at the pro comedy world, despite best efforts by star Julie Kavner (center). But this 1992 movie really soars when it concentrates on the daughters: Gaby Hoffman and Samantha Mathis (from left) as two mismatched, appealing and convincing siblings left temporarily behind by mom’s meteoric success (HBO Wednesday at noon).
