The stars of this movie are supposed to be Kirk Douglas and Laraine Day, but it's worth saying right off the top that the movie is worth watching primarily for Keenan Wynn's hilarious performance as Ronnie Hastings. He really is the one who makes this movie.
Ronnie is a neighbour of and assistant to author Owen Waterbury (Douglas.) After writing a best-seller, Waterbury gives a lecture to a writing class and meets Stephanie Gaylord (Day.) Waterbury offers Gaylord a job as his secretary, and she accepts, but what she didn't know is that Waterbury's secretaries don't last very long. He's a bit of a playboy type, and he and Hastings always insist on a certain "type" of secretary (ie, extremely cute) and most of them don't take very kindly to being hit on as soon as they walk through the door.
Basically, this movie deals with the evolution of the relationship between Waterbury and Day. Both play their parts very well, but, as I said, the show is stolen by Wynn right from the beginning, and it all leads up to an ending (again with Wynn as the comedic centrepiece) that I didn't see coming, particularly given what seemed to be Ronnie's taste in women.
All in all, it's good, clean entertaining comedy, with a plot that admittedly gets a little bit tired by the end, but still there's quite a few laughs here. 7/10
