I can't figure the ages of the characters.
When the tombstone is delivered, and I don't remember the exact dates, Books age calculates out to be late 50s. (The summary say's he's 58.) Yet, John Wayne was in his late 60s when he played the role.
When Books is talking to Bond, she says she's been a widow for a year, and her husband was only 41 when he died. While it's possible she was much older than her husband, it would have been more believable just to state her husband was 50 when he died. (Lauren Bacall was in her early 50s at the time.)
I guess you could say the actors look the ages they do because of the hard living the characters had gone through, but wouldn't it have been more believable to make the characters were just a little bit older then they originaly said?
He who fights and runs away, lives to run away again!
