News Summary: Marvel, circus, team up on live show

CENTER RING: The people who bring you The Greatest Show on Earth will be taking Spider-Man, the Hulk, Thor and the Fantastic Four on a worldwide road show. Feld Entertainment Inc., which produces the Ringling Bros. and Barnum & Bailey circus, announced a partnership with Marvel Entertainment to produce a live arena show featuring the Marvel universe of characters.

SUPER GROWTH: Feld Entertainment has expanded in recent years to acquire several motor sports and monster truck shows aimed at expanding its appeal beyond the young children who go to the circus and girls who flock to the Disney shows.

DON'T TRY THIS ON BROADWAY: Trying to bring superhuman characters to life in a live show can be daunting and even dangerous, as evidenced by the run-up to the Broadway musical "Spider-Man: Turn Off the Dark." Several performers suffered injuries ranging from concussions to fractured skulls in what became the most expensive show in Broadway history. Feld says his company is at home in that environment.
