With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Scorsese was initially reluctant to develop the project, though he eventually came to relate to LaMotta's story. Schrader re-wrote Martin's first screenplay, and Scorsese and De Niro together made uncredited contributions thereafter. Pesci was a famous actor prior to appearing in this role, but Moriarty was unknown to the producers before he suggested her for her role. During principal photography, each of the boxing scenes was choreographed for a specific visual style and De Niro gained approximately to portray LaMotta in his later post-boxing years. Scorsese was exacting in the process of editing and mixing the film, expecting it to be his last major feature.
text_B: Is it possible that the writers of this movie had specifically tailored the character to Joe Pesci's unique on-screen charisma, with the hopes that he would accept the role?
YES.
