Richard Riehle was last seen in Los Angeles in 2018, right after he had finished filming A Very Nutty Christmas. That makes the city and the movie the clearest fixed point in the record of his last public appearance.
The 2018 sighting matters because it ties the actor to a completed Lifetime holiday project rather than a promotional stop or an in-progress shoot. Melissa Joan Hart was part of the film, giving the appearance a clear production context even as the timeline stops there.
Los Angeles in 2018
2018 is the only dated reference point available for Richard Riehle in this account. He was in Los Angeles at the time, and the encounter came after he had just gotten back from filming A Very Nutty Christmas.
That sequence gives the story its structure: work first, then the sighting. For readers tracking where Riehle surfaced last, the useful detail is not just the city but the fact that the film had already wrapped when he was seen.
A Very Nutty Christmas
A Very Nutty Christmas supplies the only project-specific detail in the story. It was a Lifetime holiday movie, and Melissa Joan Hart was part of it alongside Riehle.
That pairing narrows the timeline and the context at once. The last known appearance was not tied to a public event announcement or a fresh release; it came after filming had ended, which leaves the film as the final concrete marker in the account.
Where Richard Riehle
Where Richard Riehle went after returning from filming A Very Nutty Christmas is not explained in the available details. The absence of that next step is part of the story, because the record stops with the 2018 Los Angeles sighting and does not extend beyond it.
For anyone following Richard Riehle’s trail, the practical takeaway is simple: the last verified point is Los Angeles in 2018, after A Very Nutty Christmas wrapped. Everything after that is outside this account.
