\n\n\n\n\n\n\n\n\n\n\n\n\n\n\tMany legends have graced the Actors on Actors set, but few Hollywood dynasties have collided like Mariska Hargitay\u2019s and Jamie Lee Curtis\u2019. The former is the daughter of Jayne Mansfield, the \u201950s bombshell who died in an auto accident. Her rich and complicated legacy is the subject of Hargitay\u2019s acclaimed documentary, \u201cMy Mom Jayne,\u201d from HBO, which is in Emmy contention this year. More impressive is that Hargitay pulled the film together while playing the hard-driving detective Olivia Benson on NBC\u2019s \u201cLaw & Order: Special Victims Unit,\u201d a character who has only become more iconic over the show\u2019s 27 years. The latter is the Oscar-winning daughter of screen legends Tony Curtis and Janet Leigh. Curtis has transformed over and over, from scream queen (\u201cHalloween\u201d) to \u201980s comedy icon (\u201cTrading Places\u201d) to meme-worthy mom (\u201cFreaky Friday\u201d and FX\u2019s \u201cThe Bear\u201d ). <\/p>\n\n\n\n\n\tIt\u2019s easy to imagine the pair as old friends, catching each other on the coasts and dishing over the decades about co-stars, executives and their craft. But the famous offspring only recently became \u201csisters,\u201d as they describe it. Variety<\/em> was lucky to capture how and when they sparked, and what unfolds when memory lane looks a lot like the Hollywood Walk of Fame. <\/p>\n\n\n\t\t
