Grouch,
Agreed on Mr.Roberts. He was great in Wilder films, it isn't that he only played screwball all the time. There's always drama at heart, and Wilder-Lemmon play tragicomedy/seriocomedy in their collaboration. DOWAR is a truly amazing performance. Another film where you see how the performance in B/W feels very iconic. He showed his range in later films. Of course, 70's and the new wave in general got all the classic actors to shed their iconic 'image' (and the transition to color obviously changes everything). Lemmon is superb in Save the Tiger, China Syndrome, and Missing. He aged superbly.
