Frankly speaking, conveying emotions through body language is no easier than using expressions and tone. However, there was no better method for Monica. Previously, it had been mentioned that her performance using her own demeanor was somewhat lacking, but her body language was quite good. The dance sequence with Travolta in "Pulp Fiction" was one of her best performances.
As long as Monica performed impressively, Adrian, with proper editing in post-production to fully showcase her strengths, could notably enhance her allure. Moreover, the original "Malena" mainly utilized Monica's limited screen time for body language; Adrian, while revising the script, amplified this aspect even further.
