Nathan Fillion and Stana Katic are spotted filming their ABC series Castle in Downtown Los Angeles last week (October 19). Even though the show is set in New York, it's actually filmed on the West Coast.
Castle has a special Halloween-themed episode in store for viewers tonight. Series creator Andrew W. Marlow told TVLine:
"What we're dealing with is a murder inside a old, locked haunted mansion, where the only way somebody could have killed this guy was is if they were not of this world — if they were from the other side. So we get to investigate and have a lot of fun with that."
