In the wake of the Pulse nightclub tragedy, several key members of "The Walking Dead" cast will appear at Fan Fest Orlando; the event will donate all profits to the One Orlando Fund, which benefits the victims and their families. Founder and Orlando native James Frazier's goal is to raise $500,000 for the One Orlando Fund.

Entertainment Weekly reports that Lauren Cohan, Michael Cudlitz, Josh McDermitt, Alanna Masterson, Ross Marquand, Seth Gilliam, Sonequa Martin-Green, Christian Serratos, Emily Kinney, Lawrence Gilliard Jr. and executive producer Greg Nicotero will attend. More stars will be announced at a later date. Additionally, celebrities from other shows are scheduled to make an appearance, including "Arrow's" Stephen Amell and David Ramsey.

Fan Fest Orlando takes place September 17 at the Orange County Convention Center. Tickets for the one-day event are now available on the Fan Fest Orlando website.
