RICH MAN, POOR MAN was one of the great miniseries from the mid 70s. A great villain, Falconetti (William Smith), is seen here and it launched the career of Nick Nolte, bad boy with a heart of gold.
This is the saga of the Jordache family, from the end of the war through the 1960s.
Peter Strauss is Rudy Jordache and Nick Nolte, his brother, Tom. Susan Blakely played the girl they both loved.
Based on the book by Irwin Shaw this was water cooler TV in 1976 for a couple of months.
I am not sure if I would have chosen Nolte as the actor from RMPM to parlay his role into a great acting career, but women loved him. Peter Strauss and Blakely seem to have largely disappeared except for occasional guest appearances on network TV. For more forgotten movies, see Todd Mason.
