According to PWInsider, WWE has been contacting former Superstars and personalities to film video messages for the upcoming RAW 25th Anniversary show. The company expects to either use these during the live broadcast or use them for promotional material for the event.
As previously noted, WWE is considering this show a “all-hands-on-deck” show, and they are bringing in many names for the show. The Undertaker is one of the big names being advertised for the January 22nd event, which will be simulcasted from The Manhattan Center and The Barclays Center in New York City.
