When it comes to Dick O’Neill’s career highlights, one film that really stands out is Pretty Poison from 1968—it’s widely regarded as Dick O’Neill’s highest rated movie. Critics and audiences alike have praised his performance in that role, which remains a defining moment in his filmography. On the other hand, not every project hit the mark, and among his works, Loose Cannons (1990) tends to receive the most criticism, making it Dick O’Neill’s lowest rated film to date. While opinions may vary, these two titles—Pretty Poison and Loose Cannons—represent the high and low points in terms of ratings throughout Dick O’Neill’s time in the industry.
