The only really crap film I’ve seen Russel Crowe star in has been Noah. Are there others? Tend to really like films he is in. Gladiator, A Good Year (love that film), 3:10 to Yuma and Master and Commander as standouts for me.
Off the top of my head and having not seen that many films in the last few years, probably Jack Nicholson in One Flew Over The Cuckoos Nest. Maybe Christopher Walken in the Deer Hunter. Two films that genuinely traumatised me.
