Problem of the Day Part IX

So I have still not really caught up with the good posts. I promise a lot are coming really soon!

To start today's problem, let's take up the problems from last Thursday:

1. The letter M occurs once in every minute, twice in every moment, but never in a thousand years?

2. The man does not get any hairs wet because he is completely bald.

3. All wise men, regardless of their religion or politics, agree that the word "AND" is between heaven and earth.

Alex G., Heather D. and Carly G. all get three points for their correct answers.

This installments questions are movie trivia, but the answers are not easily found (note actor could mean actress, I just used actor and assumed you realized it could be a male or a female):

1. What actor got his start playing an extremely minor role in one movie of a trilogy and then later went on to play a much bigger role in another trilogy? You get one point each for naming the actor, the first trilogy, which movie of the first trilogy and the second trilogy (4 points total).

2. This well-known actor played a lesser role in a well-known movie. The character replaced another character when the original character was unable to continue their duties. The original character also played a doctor on tv. For one point each, name: the movie, the two actors, and the tv show in which the actor played a doctor (4 points total).

As always, email your responses to pieceofdust@gmail.com with "Problem of the Day Part IX" as your subject line. I encourage those people who have yet to respond to give it a try as anything can happen...

Good luck!
