@fckggoodmovies: In an interview with Al Pacino on the DVD Special Edition of 𝐇𝐄𝐀𝐓 (𝟏𝟗𝟗𝟓), Pacino revealed that for the scene in the restaurant between Hanna and McCauley, Robert De Niro felt that the scene should not be rehearsed so that the unfamiliarity between the two characters would seem more genuine. Michael Mann agreed, and shot the scene with no practice rehearsals and with two cameras simultaneously to generate a greater level of fluidity between both men.
