The episode is *\u201cThe Cast\u201d* (Season 2, Episode 15).344 Here's the scoop:\n\n---\n\n### \u2714\ufe0f The Episode: \u201cThe Cast\u201d\n\n- **Season:** 2 (1953\u20131954) ([en.wikipedia.org](https://en.wikipedia.org/wiki/List_of_Gunsmoke_%28radio_series%29_episodes?utm_source=openai))  \n- **Episode Number:** 15 ([en.wikipedia.org](https://en.wikipedia.org/wiki/List_of_Gunsmoke_%28radio_series%29_episodes?utm_source=openai))  \n- **Title:** *\u201cThe Cast\u201d* ([en.wikipedia.org](https://en.wikipedia.org/wiki/List_of_Gunsmoke_%28radio_series%29_episodes?utm_source=openai))  \n- **Replacement Actor as Doc Adams:** *Paul Frees* stepped in for Howard McNear in this episode. ([en.wikipedia.org](https://en.wikipedia.org/wiki/List_of_Gunsmoke_%28radio_series%29_episodes?utm_source=openai))\n\n---\n\n### \u2753 Context & Reasoning\n\n**Howard McNear** was the regular actor for Doc Adams throughout the *entire* radio series (1952\u201361). ([en.wikipedia.org](https://en.wikipedia.org/wiki/Gunsmoke?utm_source=openai))  \n- According to several recorded logs and episode guides, *\u201cThe Cast\u201d* is the only one of the 480 or so *Gunsmoke* radio episodes where someone else played Doc. ([en.wikipedia.org](https://en.wikipedia.org/wiki/List_of_Gunsmoke_%28radio_series%29_episodes?utm_source=openai))  \n- In that instance, **Paul Frees**, a prolific voice actor, filled in. ([en.wikipedia.org](https://en.wikipedia.org/wiki/List_of_Gunsmoke_%28radio_series%29_episodes?utm_source=openai))  \n\n---\n\nIf you want, I can find out *why* McNear was unavailable for that episode (illness? scheduling conflict?), and whether Paul Frees\u2019 portrayal of Doc is notably different. Do you want me to dig into that?"

No credible documentation\u2014interviews, production logs, or biographies\u2014gives a cause such as illness, scheduling conflict, or something else for McNear\u2019s absence.\n\nHere\u2019s a summary of what *is* known, and what remains uncertain:\n\n---\n\n## What *is* known\n\n1. **Paul Frees filled in once** as Doc Adams  \n   In \u201cThe Cast,\u201d Paul Frees replaced Howard McNear for Doc\u2019s part. This is the only known instance where the usual actor didn\u2019t portray Doc Adams. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Paul_Frees?utm_source=openai))\n\n2. **Air date and reuse**  \n   That episode first aired on **December 12, 1953**, and the same script was later reused (a repeat) in 1958 with McNear back in the role. ([gunsmokenet.com](https://www.gunsmokenet.com/GunsmokeTGAW/Marks-Stuff/Gunsmoke/GunLog.html?utm_source=openai))\n\n3. **No record of another episode with Doc replaced**  \n   The episode list and logs confirm that \u201cThe Cast\u201d is uniquely the episode where McNear does *not* play Doc Adams. McNear portrayed Doc in effectively every other episode of the radio series. ([en.wikipedia.org](https://en.wikipedia.org/wiki/List_of_Gunsmoke_%28radio_series%29_episodes?utm_source=openai))\n\n---\n\n## What *isn\u2019t* known\n\n- **The reason for McNear\u2019s absence** in \u201cThe Cast\u201d is not documented in available sources. No interviews, cast biographies, or production notes have been found that explain *why* Frees stepped in for that one time.  \n- **No medical or personal event** has been linked to McNear specifically for that date. It does not appear to align with any well-known illness, contract dispute, or similar incident in his life recorded in standard references.  \n\n---\n\nIf you like, I could try digging into archival materials\u2014old CBS production memos or perhaps newspaper listings from that week in December 1953\u2014to see if there\u2019s something unpublished that might shed light on McNear\u2019s non-appearance. Would you want me to explore that?"
