Producers of Two and a Half Men must really want to send a message to former leading man Charlie Sheen. As if it isn't bad enough that the show will go on without the troubled trainwreck, they plan on really sending the 45-year-old out with a bang -- in more ways than one. Sheen's character Charlie Harper is scheduled to die after stepping in front of a real train. Among the women they're recruiting to appear in the debut episode where Sheen is killed off is none other than Sheen's ex-wife Denise Richards. One insider tells the Huffington Post that the actress is perfect for a cameo. Says the source, "Denise is an excellent actress who can do everything. Comedy, drama, and let's face it, she's not bad to look at either. Having her make a surprise appearance in the debut episode would be genius and the producers of the show are brilliant for suggesting it." With such hits as Scary Movie 3, Cougars, Inc., Jolene and You Stupid Man under her belt, it's easy to see why she's such a hot commodity and in such high demand by the famous sitcom. Obviously, they're the perfect fit...NOT! Everybody knows the ploy is really just another way to get under Sheen's skin. Of course, it's complicated for Richards. So far, she has reportedly shot down any offers to appear. The insider adds, "The fact she is his ex-wife and talented can't fail to work. Initially, Denise said no out of respect for Charlie but everyone is hoping she changes her mind. She did two episodes a while back but nothing would be bigger than turning up on Ashton's debut episode." Richards probably knows better than to bite the hand that feeds her...and her three children.
