Looking for the name of movie that I only saw the initial start. It seems to take place in England, and involves two families that descend from a father that is deceased. One family is legitimate and the other descends from a mistress. Two of the step sons run an international company and of course have different views. The opening scene has, I believe, 2 step granddaughters, each working for a different animal protection organization, trying to shut down a circus.
