British actor recalled ladies inside hotel, not outside (6)

'british actor' is the definition.
(Peter O'Toole)

'recalled ladies inside hotel not outside' is the wordplay.
'recalled' says the letters should be written backwards.
'ladies' becomes 'loo' ('the ladies' is a type of loo or toilet).
'inside' indicates putting letters inside.
'not outside' says to take the centre (the outside letters are removed).
The centre of 'hotel' is 'ote'.
'loo' written backwards gives 'ool'.
'ool' put into 'ote' is 'OTOOLE'.
