Which Lawrence of Arabia version from the 40s or 50s (your words) are you referring to?

If you mean the famous 60s film…. Yes, it has a minute of credits and another 4 or 5 for the overture. Not credits.

Again, still looking for examples of extended credit sequences. Overtures are basically the same as intermissions. That’s a totally different beast.

Even if you want to lump them together, we’re still at the “one or two” I mentioned. Huge Hollywood blockbusters. Exceedingly rare.
