10 Biggest Challenges WrestleMania Has Ever Faced

10. The "Sniper Threat" - WrestleMania VII

Going into WrestleMania VII, the then-WWF planned to hold the event in front of a crowd of 100,000 people at the Los Angeles Memorial Coliseum. Only that didn't happen, as the 1991 edition of the annual Showcase of the Immortals was moved to the Los Angeles Memorial Arena.

The official line given for this change of venue was due to the fear of a sniper attack on uber-heel Sgt. Slaughter. Remember, this is a Sarge who was fully in the midst of a villainous run in which he was portraying an Iraqi sympathiser at the peak of the Gulf War.

If WWE is to believed, this fear was completely and utterly genuine - and if that is indeed true, the threat of your top heel being assassinated live on PPV is clearly a major challenge.

Of course, the other school of thought from many on this is the fact that ticket sales were extremely slow for WrestleMania VII. That slow traffic on the ticket front meant the company's planned 100,000 crowd seemed extremely unlikely - and so the vastly smaller venue of the Memorial Arena was a far less embarassing home for the 16,000 people who were ultimately in attendance for 'Mania VII.
