David Attenborough’s Natural Curiosities (BBC2, 8pm)
In Animal Frankensteins, the naturalist looks at two hybrids that owe their existence to human interference. Global warming has increased overlap in the habitats of polar bears and grizzlies in Canada, resulting in the pizzly bear. Meanwhile, the Africanised honey bee or “killer bee” came into existence due to the transfer of African species to South America. Although reports have suggested they are larger than regular honeybees and have lethal venom, killer bees are actually smaller and less aggressive.
Imagine – Mel Brooks: Unwrapped (BBC2, 9.45pm)
One of his most famous movies may be about a scheme to get rich by deliberately staging a Broadway flop, but comedy legend Mel Brooks knows about scoring a hit. Following the success of the stage version of The Producers, another musical take on one of his classics, Young Frankenstein, is playing in the West End. Here, Alan Yentob calls on the now 91-year-old Brooks to learn more about his incredible career via interviews and a wealth of archive footage. The documentary is followed by a chance to see Young Frankenstein and the original version of The Producers.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
Callum Baird, Editor of The National
