Black and white classics include Citizen Kane, Casablanca and The Maltese Falcon (the latter two starring the incomparable Humphrey Bogart). I consider the first two installments of The Godfather to be without peers. I also love the John Ford westerns, particularly The Searchers and She Wore a Yellow Ribbon (both with John Wayne).
I think most of the older movies will be considered tame by today's standards. I love Citizen Kane and Casablanca. Neither movie has much in the way of sex and violence, but they do have deep, touching themes.
I love classic movies. Here are some suggestions, depending on what you're looking for:
Suspense: I love Rear Window, which stars Jimmy Stewart and is an Alfred Hitchcock classic murder mystery about a man who believes he has witnessed a murder from his rear window. Also a favorite of mine is Charade, starring Audrey Hepburne, Cary Grant, and Walter Matthau; this movie has a great blend of romance, plot twists, and action.
Musicals: Starring Walter Matthau as the stingy curmudgeon looking for a bride and Barbra Streisand as the cunning matchmaker, Hello, Dolly! is a hilarious and fun musical with a great combination of comedy and memorable songs. My Fair Lady also ranks up there as one of my all-time favorite movies ever.
Comedy: One of the best that I can recommend is the classic screwball comedy, Bringing Up Baby; Katherine Hepburn and Cary Grant are comedic gold in this movie. It's very quick-witted and tongue-and-cheek!
I ma not quite sure what is meant by "tame," but a few of my favorite classic movies are Chitty Chitty Bang Bang, Bedknobs and Broomsticks, and The Apple-Dumpling Gang. I love the themes behind the movies, and they are great family classics.
All About Eve is a classic black and white film. It's charming and fun. One of my personal favorites is a movie called Network. The writing is just great and the acting is too. Network was made in the 1970s and was popular when it was released. There may be a few lines from the movie you'd recognize.
