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.
It's implied that Jehovah's Witnesses don't watch television; Jehovah's Witnesses do not have any objections towards watching television as long as its non-violent and non-sexual content.
Based on the references to President John F. Kennedy and the Texas governor's re-election campaign, the events in this movie take place in 1962. The US paper money shown at the end of the movie and in the opening are modern post-1964 Federal Reserve Notes instead of Silver Certificates which were the only currency in circulation in 1962.

Must've moved. Probably couldn't have heard him anyway, this goddamn ear's still bleedin'. Don't you ever try that shit again.
