Sorting titles of movies

Hi all,

I want to sort my dvd database from a to z. For movies starting with a to z no problem but I have movies starting with numbers (2 Guns, 16 blocks, 8 Mile, sorted out as 16 blocks 2 Guns, 8 mile) or in case of sequels numbers behind it (star trek 1 to 12, star trek 10,11,12 sorts out before 2). I searched this forum and found several solutions but none of them worked for me so far... Can any one explain step by step how to fix this for the entire document.

Greetings Crasher...

P.S. I use Office 2013
