Watching that, it kind of looks like normal speed for Selwood and whoever is next to walla when he takes off (Goddard?). But Walla is in Benny Hill sped-up fast forward mode! While Selwood does have to bend and pick up, and so understandably is a bit slower, count the steps. Selwood takes 6 in the time Walla takes....(not kidding) 12!!
Needs a YouTube of multiple chase-downs with that Benny Hill music, I reckon.
