Has actor Tyler Williams secretly joined the cast of "The Walking Dead" without anyone noticing? The Spoiling Dead posted photos to their Facebook page on Tuesday, Aug. 26 that shows the "Everybody Hates Chris" star filming a scene with Norman Reedus (Daryl Dixon).

Apparently it was previously rumored that Williams had joined the cast but the rumor never picked up steam because there was no information about his supposed character or pictures. It's not clear who Williams will play (it could be a completely new character or a comic book character) but eagle-eyed fans spotted him in the Season 5 trailer released during Comic-Con in July.

At the end of the trailer, AMC teased Beth's storyline and fans learned that she's being held at a creepy hospital. In one scene, Beth (Emily Kinney) is seen running away from the hospital and right behind her is what looks like Williams.

"Word is people around base camp have been told/heard that Tyler Williams from Everybody Hates Chris is on set. It's been rumored for a bit now that he had landed a role," the group posted. "His tweets match up for certain dates. He also appears to be the male in the trailer following Beth out of the hospital. So far he has been in Atlanta/Griffin/Peachtree during TWD filming. He seems to fit the description of the unidentified male that was filming with Rick, Ty, Glenn and Michonne earlier today."

If Williams is a part of Season 5, he joins newbie Seth Gilliam as Father Gabriel and Christine Woods as the lady cop who slapped Beth in the trailer. So far, AMC has not officially announced Williams as part of "The Walking Dead" cast.
