I came across some press footage for Half of a yellow this week. The first is a CNN interview with Biyi Bandele who wrote the script. He talks about knowing from the start that Thandie would be perfect to play Olanna, however, it took him a few years to convince her to play the role.
The second video is an interview Thandie did with the Press Association. Here she talks about falling ill with Typhoid during filming, the hard work that goes into making a film and the demands it places on resources.
