My Sweet Charlie (1970 TV movie) From IMDb: A pregnant white Southern girl (Patty Duke) and a black New York lawyer (Al Freeman Jr.), both on the run in rural Texas, meet up in a boarded-up, abandoned house and realize they both need each other in order to survive.
IMDb review: Duke won her first Emmy award (1970) for her exceptional work in this production. Producers Levinson & Link (who were then novices), also received an Emmy for their script, as did Ed Abroms for editing. Director Lamont Johnson was awarded the coveted DGA for Best TV Director. In total, the film received eight Emmy nominations. This was not only a critically acclaimed production; it received a 31.7 rating and 48 Nielsen share.
I had to include the extra information because this is such a sadly overlooked movie that should be shown on movie channels such as Encore and Starz, as other TV productions have been. It's an impressive film.
