Jean Porter and Edward Dmytryk met during the making of this film and would be married in 1948, until his death in 1999.
The film is filled with hep jargon in use by young people during the '40s, including "groovy," which is associated with the '60s but dates back to the '20s.
The image behind the opening title credits is the Honorable Service Pin, given to U.S. servicemen who had been honorably discharged from the military during and immediately after WWII. It was given the nickname the "Ruptured Duck." Note that Harper and Tabeshaw wear the insignia on their uniforms above the right breast pocket after they are officially discharged. Servicemen were allowed to wear their uniforms for up to 30 days after leaving service due to post-war clothing shortages, and this indicated, although in uniform, they were no longer in the military.
This film was based on a novel by Niven Busch. His then-wife, Academy Award winner Teresa Wright, had a starring role in "The Best Years of Our Lives," (released months later) which covered the same plot here, and ultimately overshadowed "Till the End of Time," winning seven Oscars.
This film was a hit at the box office, earning RKO a profit of $490,000 ($6.9M in 2019) according to studio records.
