Make a mistake in Rob Reiner remake (2,2,5)

I believe the answer is:

be in error

I'm a little stuck... Click here to teach me more about this clue!

'make a mistake' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'rob reiner remake' is the wordplay.
'remake' is an anagram indicator (the letters made in a different way).
'rob'+'reiner'='robreiner'
'robreiner' is an anagram of 'BE IN ERROR'.

'in' is the link.

Can you help me to learn more?
