The storyline was great, but the acting and cinematography were, at best, lackluster. Kevin Sorbo and James Barrington did an OK job, but the rest of the cast, including Cuba Gooding Jr. were mostly awful. The actor who played the prison camp commandant, Tupua Ainu'u, never "sold" the role. One would expect his character to be hard and evil, which is what was scripted and what he tried to portray, but his execution was not convincing at all.
The casting for the prison guards was highly questionable. Given the prison was located in Indonesia, I'm not sure why so many Anglo/American actors were cast in those roles. Also, watching the guards march was both comical and painful. The director should have hired someone to teach these actors how guards in an Indonesian prison truly behave.
CBJ often appeared to compensate for the others' lack of acting prowess by "overacting." The scene where he was walking thru the prison on his way to his execution singing Amazing Grace was one of the worst scenes in the entire movie. CBJ is a seasoned professional actor who should have been able to elevate his acting skills to match the importance of that moment in the story. The director should have made him reshoot it until he captured the true essence.
It's too bad the producers did not seek out the Kendrick Brothers as directors. This could have been a great movie, but it fell way short of honoring what the actual men did for the sake of the Gospel.
