Spielberg and his wife, Kate Capshaw, have donated $100,000 to fight Proposition 8.
Also known as the Marriage Protection Act, Proposition 8 would amend the state constitution to limit marriage to a man and a woman. If passed, it would overturn the court decision that made the state only the second in the country to legalize gay marriage.
In a statement to reporters, Spielberg said:
"By writing discrimination into our state constitution, Proposition 8 seeks to eliminate the right of each and every citizen in our state to marry regardless of sexual orientation. Such discrimination has no place in California's constitution, or any other."
Last month, Brad Pitt and Angelina Jolie donated the same amount to the cause, and other celebrities have quietly donated funds behind the scenes. The Knights of Columbus, in support of the marriage ban, weighed in with a $1-million contribution in favor of Prop 8.
This amendment could have an impact on celebrities like Ellen DeGeneres, who recently married her lesbian partner Portia De Rossi, and George Takei, Star Treks Sulu, who also married his long time gay boyfriend. Other openly gay celebrities like Lindsay Lohan and Samantha Ronson have announced they would like to marry by Christmas.
