Moviemaker Steven Spielberg has followed in the footsteps of Brad Pitt by donating $100,000 (£54,000) to a campaign to keep gay marriage legal in California.

Spielberg and his wife Kate Capshaw gave the cash to the anti-Proposition 8 campaign which helps activists oppose a high-level state vote to ban same-sex marriages.

The vote is due to take place in the upcoming November (08) elections.

Gay marriages were legalised in the state in May (08).

The couple said in a statement, "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."

Pitt has also donated $100,000. (c) WENN
