The hype for this film was so high that the tickets were sold out in Japan, 5 months before the official release.
In this film Broly bears two significant marks on his body: a scar on the upper left of his abs, and a giant cross-shaped scar on his left pec. These reference his defeat in his previous appearances: Goku struck him in Dragon Ball Z : Broly le super guerrier (1993), and his heart exploded out his chest in Dragon Ball Z : Rivaux dangereux (1994).
Ricardo Brust, the voice actor for Broly in the Latin American dub, lost his voice for a few weeks after he finished recording the screams of Broly.
When Akira Toriyama began to write Dragon Ball Super (2015), he was reluctant about adding the character Broly to the franchise, instead he wrote a character named Kale, who is a Saiyan, as an homage to Broly. However one of the series producers in early 2017 convinced him to add Broly into the series, so he wrote a new story for Broly and drew a new design, so this version could be different from the original films.
According to director Tatsuya Nagamine, Akira Toriyama had written a screenplay that was 3 hours long, but the film only runs for 2 hours, so Nagamine and animation director Naohiro Shintani collaborated with Toriyama to analyze what can be kept in the film and what has to be dropped due to running time purposes.
However, there are some scenes that were animated but cut from the final theatrical film which will be added to the Blu-Ray and DVD release.
