Colin Firth, Hugh Jackman, Sir Ian McKellen and Geoffrey Rush are raising money for two schools badly damaged in New Zealand's devastating earthquake in February (11).
More than 160 people died in the 6.3-magnitude tremor, which hit the city on 22 February (11), causing considerable damage to Christchurch schools Shirley Primary and Avonside Girls' High.
Now stars including Russell Crowe, Guy Pearce, Kylie Minogue, Michael Buble and Donald Trump will help raise funds to rebuild the facilities by auctioning off one-of-a-kind collectibles and gifts for the Stars 4 Kids campaign.
The King's Speech co-stars Firth and Rush have contributed autographed DVDs, while Australian pop star Minogue has offered up signed memorabilia. Jackman is giving away a storyboard used for X-Men Origins: Wolverine and fans can also bid on a South Sydney Rabbitohs rugby cap from Crowe.
The Stars 4 Kids auctions will begin on New Zealand website Trade Me on 16 and 23 May (11).
