When Bart's mom is driving him to the camp, and Bart puts in U2's The Joshua Tree cassette tape. Then a U2 song starts to play , but the song isn't from The Joshua Tree, instead the song is" Into the Heart" which is a song from their first album Boy.

MercyMe lead singer Bart Millard started wearing glasses while he was growing up and still does today. But the movie depicts him not wearing glasses at all, even as a teenager and then an adult being played by actor J. Michael Finley.

In one of the first scenes, set in 1985, the record store owner recommended Bart to listen to U2's "The Joshua Tree" cassette. The Joshua Tree was not released until 1987. Later in the movie, Bart had a different U2 tape, Boy, which he asked his mother to play.

Bart Millard's older brother Stephen is nowhere to be seen or mentioned in this movie. This movie depicts Bart as if he were the only child - which is false.

Bart Millard's then-estranged mother Adele dropped him off to his father's house when he was in third grade, not seventh as the movie depicts.

When Bart is in the Camp Lunch Line the Cook Gives him a hot dog with fries, a few seconds later Bart turns around and now has a burger and fries on his plate.

Bart tells his Dad that he will be singing at the church and he can listen on AM 1080. Every scene in the movie that shows his Dad's radio shows the band switch in the FM position, not the AM band.

At the scene when you see WJDC Studios with the board faders on the PR&E Radiomixer-12 console down and the off lights (yellow colored) out, but still hear audio, that's the production room being shown and the jock 2 rooms barely seen down the hall has the station live in the on air room.

Young Bart is handed the U2 album The Joshua Tree (1987) in 1985.

The version of "Hallelujah" the Glee club was singing in 1991 is based on Jeff Buckley's 1994 rendition.

In the 1985 scenes, the record store has a poster in the window for the first .38 Special record. This album came out in 1977, and was not a big commercial success at its time of release; its popularity was eclipsed by the band's subsequent releases. Additionally, it was already horribly out of date by the time this scene is set; no record store would be likely to display a poster for an album eight years old that was not commercially successful.

The timing based in the movie is supposed to be in 1999 when radio stations have an older system of the "Emergency Alert System" in place. At KMGL, they have a new blue digital EAS-CAP box called "Sage Digital Endec" which is incorrect for the timing of the movie because in 1999, Sage had a gray box called "Sage EAS Endec" in place, almost a decade prior to when they made the new blue emergency alerting encoders.

When Bart meets Amy Grant for the first time he calls her "Miss Bart" instead of Miss Grant.

Amy tells the audience that they will be the first to hear I Can Only Imagine, but others have heard Bart's demo which was recorded in front of a live audience.

This movie's portrayal of characters in terms of physical appearance is historically inaccurate when compared to what they looked like during the actual events of the story.
