Two non-goofs

Two of the listed "goofs" are questionable:

The dialogue that mentions that the Zulus won't fire their guns from the hills for fear of hitting their own men is not contradictory to the earlier "counting our guns" tactic. In that case, losing warriors to count guns was logical, though extreme, since it was a positive tactic. But losing men to errant shots from the hills was a negative tactic, which accomplished nothing.

The other non-goof involved the "and introducing Michael Caine" credit. Even though it was not his first role, common practice at that time was to use the "introducing" title for some actors appearing in their first major roll.
