“Iron Man 3″ has finally made it to Hollywood — with reshoots this week at the Chinese Theater and on Hollywood Boulevard after most of the film was lensed in North Carolina.The Marvel tentpole, which Disney opens May 3, obtained shooting permits for Monday night and early Tuesday under the production name “Caged.” Several videos posted to YouTube showed shooting of a typical street scene, followed by an explosion at the Chinese with pedestrians running and cars on the street crashing. Shooting on the Robert Downey Jr. starrer began in May in Wilmington, N.C., and included shoots in Florida and Beijing. Overall location shooting last week was moderate at 674 permitted days, according to figures disclosed Tuesday by the FilmL.A. permitting agency, as all major categories posted slight gains over the same week a year ago. “Walk of Shame,” the Lakeshore/Sidney Kimmel comedy starring Elizabeth Banks, led in feature activity for the second week in a row with 21 days — the same number as “A Dog Named Suki.” TV gained 5% for the week. As usual, a reality show led the way as “Push Girls: Season 2″ was the most active with 29 days, while drama “Southland” generated 22 days of location shooting.
