Dreyfuss/Kline

I have never found any resemblances between Richard Dreyfuss and Kevin Kline in the past. But in this movie, Dreyfuss's hairstyle wasn't the only thing that made me think of Kline. Dreyfuss's expressions and even his cadence of speech were different than usual and kept reminding me of KK. Anyone else note the resemblances?
