Butch (Kevin Costner) and Philip visit a Friendly Dept. Store, outside of which there is a poster advertising Bull Durham cigarettes. Kevin Costner starred in Bull Durham.
Early in the movie, references are made to President John F. Kennedy visiting Texas and the governor running for re-election. Unless the events in the movie take place in an alternate universe, this was not JFK's final, fateful trip to Texas. From 1876 to 1972 Texas governors served two year terms, which means this movie took place prior to the November 1962 election. JFK was assassinated in Dallas a year later in November 1963.
