The sentence
The first time when I drove was at driving school.
consists of the subject "the first time when I drove" (a noun phrase referring to a past event), the copula "was", and the subject complement "at driving school" (an adverbial phrase describing a time and/or a place). That is to say, it has the same overall structure as, say, the following sentences:
The box was on the table.
The party was at John's house.
My birthday was last week.
The subject "the first time when I drove" is probably best analyzed as a single unit — specifically, as an instance of the idiomatic pattern "the [ordinal] time (when) [something happens]", as in:
the second time (when) Alice rode a bicycle
the next time (when) I go to France
the last time (when) it rained here
(In all these phrases, the word "when" is optional; the choice whether to use it or not is a matter of personal preference. I would usually omit it, since I find that to sound more natural, but sometimes including it can reduce ambiguity.)
What about your sentence, then?
** Dracula when I saw was the latest/last movie.
This sentence would seem to have the same overall subject–copula–complement structure as above. However, the putative subject, "Dracula when I saw", is not a meaningful or even a syntactically valid noun phrase, so the sentence is not grammatical.
When you meant to write, as suggested by oerkelens in their answer, is presumably something like:
Dracula, when I saw it, was the latest movie.
or:
When I saw it, Dracula was the latest movie.
or even:
Dracula was the latest movie when I saw it.
In all of these sentences, the subject (of the main clause) is simply "Dracula". The dependent clause "when I saw it" is not a part of the subject here, but simply augments the entire sentence to indicate that it applies to a specific time in the past.
Note that the word "it" within this dependent clause is required, since the verb "saw" normally requires a direct object. Here, this object is the same as the subject of the main clause ("Dracula"), so we can simply refer to it using the pronoun "it". Of course, one could also write, say:
* When I saw Dracula, Dracula was the latest movie.
but such repetition sounds very awkward, and should normally be avoided.
As for whether to use "latest" or "last" here, I would use "latest", since it specifically means "newest" or "most recent", which is presumably the sense you intended here.
The problem with using "last" here is that it leaves the sentence ambiguous — it doesn't specify of which set of movies Dracula was the last one. Some plausible ways to continue the sentence, in order to make it unambiguous, might include:
...the last movie shown that day.
...the last movie I watched before going home.
...the last movie released that year.
Alas, none of those really match your (presumably) intended meaning, although the last one comes close. You could say something like:
* When I saw it, Dracula was the last movie released so far.
but, while understandable, using "last" like that (referring to a time interval that ends at the time being described) doesn't really sound correct to my ear. It would be much better to replace it with, say, "newest" or "most recent" or, indeed, "latest".
1Dracula was the latest movie that i saw. - And as a question -'Which is the latest movie that you saw?' – Leo – 2014-10-30T12:53:58.767
2The first time i drove was at the driving school. (when is not needed and 'the' is necessary) – Leo – 2014-10-30T12:55:37.833
1'The last movie I saw was Dracula' to avoid ambiguity of latest not being the recent most in the series. Also, latest has a flair of 'advanced' whereas 'last' talks about the last thing you did! – Maulik V – 2014-10-30T12:55:40.583
@Leo : Would you please modify as quit a bit little or very small? – Carter – 2014-10-30T12:56:46.503
2what do you want me to modify? could u be a bit specific ? – Leo – 2014-10-30T12:59:02.633
@Maulik V : Thanks. That's what am I say. So what do give to you ambiguity? I don't understand what is different between 'The last movie I saw was Dracula' and 'Dracula I saw was the last movie.' – Carter – 2014-10-30T13:03:04.957
@Leo : you totally modify my sentence structure. So I can't recognize what am I wrong. I just want you like Maulik V do. – Carter – 2014-10-30T13:07:06.807
@Maulik V : I have one more question. How about this? The Dracula I saw was last movie. If wrong, please let me know why. – Carter – 2014-10-30T13:10:41.997
@Leo : Which one is more strong have feeling between need and necessary.? – Carter – 2014-10-30T13:13:23.770
2@Leo, I don't agree that "the" is necessary. – Millie Smith – 2014-10-30T16:29:49.593
1@Leo: No, that "the" is awkward and you wouldn't tend to use it. c.f. "I go to school" instead of "I go to the school". – Lightness Races in Orbit – 2014-10-30T17:05:00.123
1indeed it is ! it's awkward that's why it's unnecessary – Leo – 2014-10-30T17:11:44.697
1I'd say that "the" in driving school is optional there: "at driving school" is more time-oriented, like "when I was taking driving school", whereas "at the driving school" is more place-oriented, suggesting a particular location that your driving school was at. – amalloy – 2014-10-30T19:17:50.383
I said the ambiguity of 'the last' and 'the latest'. Hope it's clear now. – Maulik V – 2014-10-31T04:44:42.173
@Maulik V : but how about this sentence ? The first driving was when I was 20 years old. – Carter – 2014-10-31T06:23:12.360
2Why make it complex? When I drove [vehicle] for the very first time, I was 20! OR I was 20, when I drove a vehicle for the very first time. – Maulik V – 2014-10-31T06:45:52.547
@Maulik V : please let me know is this right? 1.The first driving when I was young at 20 years old. 2. The first driving was when I was young at 20 years old. Which one is correct sentence? – Carter – 2014-10-31T07:07:15.570
3I'm sorry. None! Try to understand The first driving is not a good phrase in this context! You got it? – Maulik V – 2014-10-31T07:29:36.093
