Kendall - as for Robin and Marian I did some checking on that as well. This is a cut and paste from my posting on the thread discussing Russel Crowe's accent in the latest Hood film :-

Actually the thing that I find ridiculous in the Robin Hood films is usually the age of the actors.

Just for curiosity I checked some dates. King John - born 1157, became King 1189 (age 32) (also start of 3rd Crusade), Imprisoned Late 1192 (on way home from Crusade) until early 1194 (age about 37) Died 1199 age 42.
When he was the same age as the actor playing him in this particular film (the Russel Crowe film), he had been dead 6 years.
King John - age 22 at start of Crusade, and almost 27 when Richard released after ransom, so an actor age 30 a bit closer.

In the 1976 film Robin and Marian, Sean Connery and Audrey Hepburn play an aging Robin and Marian after the death of King Richard. (I know the plot is all hokum, but bear with me). The whole point of the film was that Robin (in terms of 12th Century lifespan) was getting old and worse for wear. How old was Connery? 46!
Back to the current new film - How old is Crowe? 46!

Quack!
