I seem to be posting a lot of these clip montages lately . . . but, as someone who adores dance in film, I couldn’t resist this one. From Fred-and-Ginger to Bob Fosse to “The Red Shoes” to “Flashdance” to Hugh Grant shaking it in “Love Actually” to the Jets and the Sharks — all for just a second or two each — it’s all here, with the Bee Gees to boot. It’s Monday — get up and dance!
