However, it seems clear based on Dimitri Thivaios’ comments that Stallone had almost a director’s perspective on the film, paying attention to everything that was happening on set.
Sylvester Stallone shares a screenplay credit on Rambo V: Last Blood in addition to starring as the lead, so he’s much more than simply an actor here.
While Stallone isn’t the director here, he’s had more than his share of experience in the job, and thus probably uses those skills at all times.
