Michael Jackson could earn more than $400m (£283m) from a comeback deal involving new music and movies as well as concerts, his promoter has revealed.
The pop superstar has announced 10 gigs at the O2 arena in London this summer.
Randy Phillips, head of AEG Live, which is staging the gigs, said they had a wider deal that could cover a world tour and a 3D film based on Thriller.
He also said: "We're talking to him about helping him figure a new plan for the release of singles, new music."
Jackson appeared at the London venue on Thursday to announce his comeback concerts.
He billed them as "the final curtain call" and "my final show performances in London".
Speaking afterwards, Mr Phillips said: "These will be the last shows in London. Whether he will go on from here around the world... this will be his last tour.
"All he's agreed to are the London shows at this point."
He said AEG Live had a "broader relationship" with Jackson.
"We have a film development deal that's part of this to do a film, Thriller 3D," he said.
It would be a new film that could star Jackson himself, he said.
Asked how much Jackson could earn from the ventures, Mr Phillips replied: "If we complete the full three-and-a-half year plan, he could gross over $400m in that time. London could be north of $50m (£35m)."
The star made a five-minute appearance in front of hundreds of screaming fans on Thursday to announce the 10 London dates.
