William Hartnell, who often forgets his lines, once accidentally says "fornicator", rather than "fault locator".

None.

None.

Contains frequent use of mild British profanity.

About 20 uses of bloody

1 use of arse

Hell, damn, and bugger are also used. The stronger curse "Goddamn" is used at least twice. The name "Christ" is used irreverently

Period-appropriate smoking. Which means, much like Mad Men, which is set in the same era, that nearly every adult character is shown smoking.

One main character is never seen without a cigarette in his mouth.

There is a scene in a pub with drinking and heavy smoking.

Several scenes show characters toasting with champagne.

One scene shows Hartnell drinking at home and possibly inebriated.

No drug use whatsoever.

Not too bad.
