This very dated 1966 Ann-Margret comedy was part of a late 60s trend in which big studios tried to tap into the market of young, rebelious "swinger" teens (whether this market ever actually existed is open to debate). Ann-Margret plays a aspiring writer attempting to sell a tell-all article on swinger culture to a Playboy type magazine. When the publisher correctly assumes that she is too innocent to have experienced what she writes about, she tries to prove him wrong by joining the swinger underground. The most famous seen is when Ann-Margret joins an orgy and gets used as a human paintbrush (this was all pretty scandalous back in the day). The plot is pretty dopey, but Ann-Margret brings a lot of energy to the role and there are a few decent gags. If you have a taste for camp and can stomach a huge dose of bad 60s fashions, it might be worth a watch.
