Music biopics in general don't make huge amounts of money. The Queen movie was a fluke. Besides the recent Oppenheimer, no other biopic of any type (music or not) made close to it. Before the Queen movie, the highest grossing music biopic was Straight Outta Compton about hip hop group N.W.A., which has made $201,634,991 worldwide. Going by that, then the Bob Marley movie did fairly well, especially since today very few non-IP movies make much money in theaters. Unless you count Chinese made movies in China. I think the 2022 Elvis Presley movie has passed up the N.W.A. one for 2nd place, but movie tickets cost more now than in 2015.
