The news of Kenny Baker's passing marks the hard reality that the original Star Wars movie was released in 1977 - almost 40 years ago - and many of the original cast have either since also passed on, or are now very old.
I think we tend to forget that with people in movies or TV shows; we see them at a certain time in their life and career, then when we see them 10, 20, or 30 years later, we are a bit shocked to see how they have aged.
Mr Baker was never really on screen in person in the Star Wars movies as he was acting inside the little droid R2-D2, wobbling from side to side or twirling the "turret" head. Regardless, he helped realize the character of the plucky little robot.
Kenny Baker had a great smile and an even greater attitude. Born at a time when little people (was less than 4 feet tall) were not expected to have much of a life expectancy, he went to have a TV and movie career and lived to be 81 years old.
