It's always an interesting move when real-life families act together, especially when they are playing families. At times, it can feel like a cynical vehicle for a younger or less-talented actor to ride the coattails of their elders; at others, it can be a really compelling choice that takes advantage of the natural chemistry they have together. Sometimes, it just works out well because of physical resemblance, such as Dascha Polanco's daughter playing her younger self in Orange is the New Black, or James Cromwell's son doing the same in American Horror Story. It has been over 20 years since Michael Douglas shared the screen with his son Cameron in the comedy It Runs In The Family. Their casting there was boiled down to a "gimmick" and not much more. It's true, there is nothing particularly special about their latest outing, Looking Through Water, or any particular reason why this is the movie where none other than Douglas's son would suffice. Perhaps it is a step in the rehabilitation of his image and their familial relationship after some troubled times, in which case this movie, about fathers and sons rediscovering each other, is a pretty splendid choice.
