Mel Gibson,Danny GloverJoe Pesci,Rene Russo,Chris Rock, and Jet Li
24 February 2008 | by disdressed12See all my reviews

out of all four movies in the series,this is probably the loudest and most chaotic,but that doesn't mean it was a bad movie.i think the storyline was a bit thin and not really all that original,but just like in part three,the action,and the chemistry of the stars makes up for that.and this movie also has more laughs than the previous installments,many courtesy of both Joe Pesci and Chris Rock.Rene Russo is back,along with Mel and Danny.Jet Li joins the proceedings in this one,and brings some spectacular fight scenes courtesy of his martial arts skill.i don't know if this is the best of the series,but i thought it was as good as number three,which i really liked.for me,Lethal Weapon 4 is a 7/10
