Keanu Reeves is a living example of why actors hate to be typecast. He played a flake in Bill and Ted’s Excellent Adventure, so when he tries a serious dramatic role, such as The Lake House, some in the audience just keep expecting him to start rambling about that sock rates guy and that beeth oven guy.
I just produced an indie documentary about the US drug war, and my DP refuses to do the sequel, wanting to do a zombie flick instead, as he fears being typecast as “that weed guy”. It’s a serious problem indeed, if one wants a career. Of course, Keanu could try producing an indie film or two, and maybe play some more-experimental roles
