True, in the movies. All that blue shifted light would require wearing a lot of sunscreen..... Also wormholes. Not stable or traversable unless you've got a negative energy device.

In the Movie they spent around 3 hours on the planet, 23 years passed on Earth during their visit.

That's handy to know. With roughly pi x 10^7 seconds per year, 3,600 seconds per hour that gives a blue shift of 6x10^4. So the cosmic microwave background of ~2.7K would have a black body radiation temperature of ~160,000 K. That's a little warm for any protective gear.

Oh, they'd help until they melted!

Also this is a low temperature that only applies to the BH from Interstellar WITHOUT an accretion disk. The internal temperature of an accretion disk is much, much higher than 2.7 K, more like millions K. The perfect sound track for a BH orbiting planet is supplied by Johnny Cash......
