What Althea Gibson and John Wayne had in common
Both took on demeaning and ludicrous roles for money.
The difference is that Gibson had trouble making ends meet because there was no professional tour for women at the time she became world tennis champ. In her life, racism may have held her back as well.
Whereas Wayne was an outrageous spendthrift and sucker who had no sense when it came to money management. Shamefully - considering the millions he had already earned over the course of several successful decades in film - he was broke at the time he made this movie.
