A hit musical production that first landed on Broadway back in 2003 just notched a couple of milestones. Variety reports that “Wicked” recently topped $4 billion in worldwide box office receipts, with the achievement coming on the heels of the production’s clearing $1 billion in sales for the Broadway production alone.

The report notes that “The Lion King” remains No. 1 all time in worldwide gross, having pulled in $6.2 billion as of late 2014.

“Wicked,” an alternative version of the “Wizard of Oz” story, is based on the 1995 novel “Wicked: the Life and Times of the Wicked Witch of the West,” by Gregory Maguire.
