I was interested to go back and review BK's reactions to the film. The endless George Segal stuff -- yes, that's it! Totally agree. One scene of that was enough. Or maybe even too much. If you excised those scenes, or the whole character, there might be just enough on the cutting room floor to get the pacing and the rest of the film in balance.
I was floored by Vivien Leigh. What a stunning woman, and role.
