"Bloodline", based on a novel by "I Dream of Jeannie" creator Sidney Sheldon, probably qualifies as one of Audrey Hepburn's lesser movies. Hepburn plays the heir to a pharmaceutical company who becomes a marked woman following her decisions about the company's future. I didn't find it a terrible movie, but Hepburn obviously starred in much better films (much of the movie seems like a rehash of her earlier movie "Charade"). She and co-star Ben Gazzara later co-starred in Peter Bogdanovich's bizarre "They All Laughed".
Director Terence Young is probably best known for "Dr. No" and "From Russia with Love". He didn't hit the bottom with this flick, but I doubt that anyone would want to stress it in their resumes. Usually I would say that there would be an incentive to remake it to try and do it right, but I actually don't like the idea of remaking an Audrey Hepburn movie. Since everyone is bound to have a few bad spots on his/her resume, we can leave it at that. "Bloodline" is still a pretty enjoyable movie, if not a masterpiece.
