Where can I watch Plaza Suite in United States?

Film version of the Neil Simon play has three separate acts set in the same hotel suite in New York's Plaza Hotel with Walter Matthau in a triple role. In the first, Karen Nash tries to get her inattentive husband Sam's attention and help save their failing marriage. In the second, brash film producer Jesse Kiplinger tries to seduce his former one-time flame Muriel. In the third, Roy Hubley and his wife Norma try and persuade their daughter, a bride to-be with cold feet, out of the bathroom before her approaching wedding ceremony.
