Director Jonathan Lynn has a law degree from Cambridge University,[9] and lawyers have praised the accuracy of My Cousin Vinny's depiction of courtroom procedure and trial strategy,[10] with one stating that "[t]he movie is close to reality even in its details. Part of why the film has such staying power among lawyers is because, unlike, say, A Few Good Men, everything that happens in the movie could happen—and often does happen—at trial".[11] One legal textbook discusses the film in detail as an "entertaining [and] extremely helpful introduction to the art of presenting expert witnesses at trial for both beginning experts and litigators";[12] furthermore, criminal defenders, law professors, and other lawyers use the film to demonstrate voir dire, relevance, and cross examination.[13][10][14]
