Age is a funny thing. When we are young, we want to be grown up. When we are old, we wish to be young again.
In the 1996 movie, Jack, Jack Powell(Robin Williams) has an unusual medical affliction. He ages four times as fast as other children age, which creates a unique set of challenges.
This is the quintessential Robin Williams film. Mingling with the humor is the reality that life is not always fair or happy. In the end, Jack knows that while he may have the mentality of a 10-year-old, his body is that of a 40-year-old. At the end of the film, the audience is reminded that life is short and we should make the most of it while we can.
I recommend it.
