The Movie-TV Connection Game (February 2016 Edition)

What's the link between Clark and Jack?
Welcome to the newest installment of one of the Cafe's most popular features. As always, you will be given a pair or trio of films or performers. Your task is to find the common connection. It could be anything--two stars who acted in the same movie, two movies that share a common theme, etc. As always, don't answer all the questions so others can play, too. There is a single best answer for each question.

1. Clark Gable and Jack Lemmon.

2. Jeanne Crain and Jean Arthur.

3. Christopher Lee, Boris Karloff, and Lon Chaney, Jr.

4. Horror Hotel and Psycho.

5. Imitation of Life (1959) and the film The Godfather.

6. Audie Murphy and Ray Charles.

7. Thunder Road and Big Jake (there are at least two connections, one obvious and the other one kinda fun).

8. Planet of the Apes and Saboteur (an easy one!).

9. Wee Willie Winkie and Imitation of Life (1959).

10. Algiers and The Magnificent Seven.

11. Don Johnson and Kurt Russell.

12. Humphrey Bogart and Rock Hudson.

13. Dirk Bogarde and Steve McQueen.

14. I Was a Teenage Frankenstein and Seven Days in May.

15. Steve McQueen and Robert Fuller.
