What Went Wrong Here?
All I remember was the massive opening and than the film fell of the planet.
From boxofficeguru in 1999:
"Moviegoers spent $20.5M watching Arnold Schwarzenegger battle Satan in the new supernatural thriller End of Days. The Universal release finds the action star protecting a young woman who was chosen to mate with the devil before the year 2000. Opening in 2,592 theaters, End of Days averaged a fiery $7,918 per site and grossed $31.5M over the five-day weekend. While the opening performance was very good, it was not spectacular and did not reach the Friday-to-Sunday heights of many of Schwarzenegger's previous action films. Terminator 2 debuted with $31.8M in 1991, True Lies opened with $25.9M in 1994, Total Recall premiered with $25.5M in 1990, and Arnold's last headlining film Eraser debuted with $24.6M. All four of those pictures were summer releases while his winter films have usually been comedies.
Universal reported that End of Days fared best with the male action crowd and performed well across ethnic and urban areas. Once the world's biggest box office star, Schwarzenegger needed a hit in order to justify his stature in the industry and to prove that unlike his action hero peers (Stallone, Seagal, Van Damme) he can still draw large audiences into the multiplexes with an explosive thrilling picture. The R-rated End of Days, which also starred Robin Tunney and Gabriel Byrne as Satan, was backed by an aggressive marketing campaign and was released at a time when people have the end of the millennium on their minds.
According to Universal, End of Days carries a production cost of $83M though other reports have pegged it at $100M. Whatever the accurate budget, the studio covered 40% of the cost and is handling domestic distribution while Buena Vista International has the picture internationally. Schwarzenegger action flicks tend to gross about 55-60% of their worldwide totals in overseas markets. Since End of Days deals with the coming of the year 2000, BVI is wasting no time rolling out the film around the world with simultaneous launches this weekend across Scandanavia, Italy, Argentina, and Singapore. Arnold and Satan will invade Germany, South Korea, Malaysia, and the United Kingdom in the coming weeks hoping to wreak havoc on a global scale.
