In the film "The Right Stuff", which actor played US Vice President Lyndon B. Johnson?

The 1983 American epic historical drama film "The Right Stuff" was written and directed by Philip Kaufman; it was based on the 1979 book of the same name by Tom Wolfe. The film follows the Navy, Marine, and Air Force test pilots who were involved in aeronautical research at Edwards Air Force Base, California, as well as the Mercury Seven. The men were seven military pilots who were selected to be the astronauts for Project Mercury, the first human spaceflight by the USA. The film stars Sam Shepard, Ed Harris, Scott Glenn, Fred Ward, Dennis Quaid, and Barbara Hershey; Levon Helm narrates and plays Air Force test pilot Jack Ridley. It's interesting to note that Donald Moffat (December 1930 – December 2018), a British-American actor with a decades-long career in film and stage in the US plays US Vice President Lyndon B. Johnson.

"The Right Stuff" was however a box-office bomb, grossing about $21 million (domestically) against a $27 million budget. Despite this, it received widespread critical acclaim, and was nominated for eight Oscars at the Academy Awards, four of which it won. The film was also a huge success on the home video market. In 2013, it was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". The film was ranked No.19 on the American Film Institute's (AFI) most inspiring movies.
