Electrical Power

Just watched on the TCM site this short from M-G-M about the Colorado River, the Boulder (now Hoover) Dam that blocks it, and the electricity that the water from there generates to provide power in seven states including the one that M-G-M resides in. Then we go to the studio itself where we see the set for The Wizard of Oz where Dorothy meets the scarecrow (alas, Judy Garland and Ray Bolger are nowhere to be seen). We also go to a few other sets as well as see technicians lighting a screen test for a forgotten actress who appeared with Mickey Rooney in The Adventures of Huckleberry Finn. Then it's on to brief snippets of previews of other upcoming M-G-M features before The End flashes on the screen...Nice views of the river, dam, and electrical towers abound in the beginning before we go to the generators of Leo the Lion's studio and then on to good closeups of the various stars on the studio roster in their upcoming movies. Worth a look for anyone interested in these old studio promotion shorts.
