In the scene were Billy is explaining the moon landing to his father, he anticipates Marie's line, "If you ask me it's the most chauvinistic exercise in the history of the world." (He turns to look at her before she starts speaking even though she is interrupting the conversation.)
The dish that was filmed in the movie is the up to date version of the radio telescope, with a larger diameter white portion in the center of the dish. The dish in the original old black and white photos behind Mayor Bob and the Prime Minister in the hallway had a much smaller white center portion to the dish antenna.
St. John's Anglican Church in Parkes (actually Forbes) was the primary location for church shots, and the service on the Sunday before the moon landing was shot indoors there. However, following the service, the parishioners are seen exiting St Andrew's Presbyterian Church instead of St. John's. Both churches are on the town square. St. John's could not be used on the shooting day since the church was being used for a funeral.
Archive footage of the ascent stage of the lunar module lifting off from the moon is not from the Apollo 11 mission. The first images of such a lift-off (showing an exterior view of the lunar module) were made using the camera mounted on the wheeled lunar roving vehicles, only carried on later Apollo missions 15, 16 and 17.
Although shown as such out the window of the antenna control room, the Moon was never full during the Apollo 11 mission.
There was no US ambassador to Australia in July 1969. William H. Crook had resigned in 1968 but stayed on until April 1969. Walter Lyman Rice was not appointed until September 1969.
The first pictures of the moon walk didn't come from Parkes, but from another tracking station called Honeysuckle Creek.
40 minutes into the film, Mayor Bob McIntyre puts a record on and dances with his wife to Blood Sweat & Tears' 'You Made Me So Very Happy'. But BS&T recorded exclusively for CBS/Columbia at the time and the record on the turntable is clearly a red label Decca pressing.
At the end of the opening sequence, Sam Neill as the older Buxton removes his hat revealing his thinning white hair: the ridge of the bald cap Neill has been fitted with is visible.
During the classroom scene at the beginning of the movie the first student describes the moon landing and a battle with aliens which involves Lasers. Whilst Lasers had been invented, their commercialisation and popular use was not yet prevalent. A more appropriate term would have been Ray Guns.
When the antenna is moved for the first track, during the segment where the machinery is shown starting, two labels "STOWED" and "FREE" can be seen. These are modern (Brother brand) P-Touch labels.
The young army cadet Keith is seen practicing his rifle drill, using the "Slope Arms" position. Slope Arms was replaced by "Shoulder Arms" in the mid'60s with the introduction of the SLR rifle and was no longer used by Australian Army Cadets in 1969, despite them still using .303 rifles
The song "Wings of an Eagle" was released in 1972, three years after the Apollo 11 mission.
When the band are rehearsing for the ball and play their Jimi Hendrix song, the guitarist's strumming does not match the music.
When Janine exits the car after she has arrived at the dish facility, the shadow of some equipment falls on the hood and roof of the car.
On the blackboard showing calculations for finding where Apollo 11 is the word parallax is spelled "parrallax".
Near end of film when high winds hit Parkes, a welcome banner stretching across the main street says "Welcome Prime MinAster", i.e., "Minister" is misspelled as "Minaster" on the banner.
Young Billy repeatedly refers to the Apollo launch vehicle as the 'Saturn V rocket' (pronouncing it as in the letter). The 'V' was the Roman numeral for 5 and was always pronounced as the number.
Keith performs a left "about turn" outside the mayor's house. A dedicated cadet as he was knows well that it is always a right "about turn".
