Double or Nothing (1936)
*** (out of 4)
Oscar nominated short has a stunt double (Phil Harris) being knocked out on set and then taken to the dentist where he is given sleeping gas. The double then goes to "Double's Heaven" where we get to see all sorts of famous stars but here they are played by their doubles. Not all of the gags work but this is a pretty entertaining short for film buffs. The Mae West bit is probably the best.
If you're interested in this film then Turner Classic Movies usually shows it once a year.
It's worth viewing if you come across it.
