A moment of grief has taken over the set of Riverdale. After Luke Perry‘s tragic death on March 4, the show stopped production, Life & Style has learned. The beloved actor portrayed Fred Andrews on the CW series and played a key role. There is no word yet on what will happen to his character on the show. The star passed after he suffered a massive stroke and his costars and fans are mourning his loss.

“We are deeply saddened to learn today about the passing of Luke Perry. A beloved member of the Riverdale, Warner Bros. and CW family, Luke was everything you would hope he would be: an incredibly caring, consummate professional with a giant heart, and a true friend to all. A father figure and mentor to the show’s young cast, Luke was incredibly generous, and he infused the set with love and kindness. Our thoughts are with Luke’s family during this most difficult time,” show producers Greg Berlanti, Sarah Schechter, Roberto Aguirre-Sacasa, and Jon Goldwater said in a statement.

Tributes to the iconic actor started pouring in from the show. “Luke Perry … you were a joyful and vibrant soul. You will be missed but most certainly your legacy will be remembered forever. Rest in love and peace, friend,” the Riverdale Writers Room tweeted.

His on-screen wife in the series, Molly Ringwald, also sent her condolences. She wrote, “My heart is broken. I will miss you so much Luke Perry. Sending all my love to your family.” Another one of his costars from the hit series, Mädchen Amick, called for fans to be courteous to those mourning, including Perry’s two children Jack, 21, and Sophie, 18. “Please. I beg of you to show Luke’s beautiful family the respect and privacy that they deserve during this devastating time. Sending love to them,” she said on Twitter.

Obviously, the show will not be the same without the actor and he will be greatly missed.
