You say you want to remove useless repeated data, but the code you are using replaces every copy of the data (not just repeated data) with a <space> character (even if the data you want to "remove" is at the start, at the end, or in the middle of a longer string.
Please be very clear about:
whether you want to replace occurrences of the strings you find in a file with a <space> character or want to remove occurrences of those strings,
whether you want to replace or remove all occurrences you find or just want to remove duplicate occurrences,
whether you want to replace or remove occurrences even if they are in the middle of larger "words", only if they are separate "words", or only if they are the complete contents of an input line of text, and
whether you want to remove lines that have been turned into blank lines or empty lines by the changes made above or keep those blank or empty lines in your updated file.
If you want to completely remove complete lines of matched text (as in your example), consider using something more like:
to do the entire job in one pass instead of one pass per word "removed". If you aren't removing complete lines, consider using awk to process each input file once instead of using sed to process each input file once per word to be "removed".

sed "/$titlesearch/d" movielist
will delete any line in the file movielist that matches $titlesearch, but this is only a screen print correct ?
how can I have sed to actually delete the line from the file so that it doesnt appear next time I open the file ?
thanks

item_count
items(3MENU)items(3MENU)NAME
items - make and break connections between items and menus
SYNOPSIS
#include <menu.h>
int set_menu_items(MENU *menu, ITEM **items);
ITEM **menu_items(const MENU *menu);
int item_count(const MENU *menu);
DESCRIPTION
The function set_menu_items changes the item pointer array of the given menu. The array must be terminated by a NULL.
The function menu_items returns the item array of the given menu.
The function item_count returns the count of items in menu.
RETURN VALUES
The function menu_items returns a pointer (which may be NULL). It does not set errno.
The function item_count returns ERR (the general curses error return value) if its menu parameter is NULL.
The function set_menu_items returns one of the following codes on error:
E_OK The routine succeeded.
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_NOT_CONNECTED
No items are connected to the menu.
E_POSTED
The menu is already posted.
E_SYSTEM_ERROR
System error occurred (see errno).
SEE ALSO ncurses(3NCURSES), menu(3MENU).
NOTES
The header file <menu.h> automatically includes the header file <curses.h>.
PORTABILITY
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
The SVr4 menu library documentation specifies the item_count error value as -1 (which is the value of ERR).
