It looks like CBS will give one of its most successful series ever, veteran crime drama CSI, a final act. I hear the network is discussing different scenarios about a final installment of the venerable procedural, and one of them that has been getting traction involves a two-hour movie that would wrap the stories for the characters and give the show a proper send-off. A short 16th and final season, as short as 6 episodes, may also still be on the table.

Additionally, sources feel bullish about the odds of spinoff CSI Cyber starring Patricia Arquette. I hear the midseason series, which has done so-so in the ratings, may undergo some retooling but it looks likely to return for a second season, being part of one of the most lucrative TV franchises in history that has brought in over $1 billion for CBS.

In the Season 15 finale of the mothership CSI, which aired in February and clearly was not intended as a series finale, Elisabeth Shue’s character is in a coma, with her fate left hanging in the balance.

By getting a proper good-bye, CSI would break the pattern of long-running and hugely profitable franchise crime procedurals getting abrupt cancellations with no send-off, which was the case with NBC’s Law & Order and CBS’ CSI: Miami and CSI: NY.
