1) does Mr Grant, a lollipop man, win the lottery? 2) is Lieutenant Frank Ballinger a plain-clothes detective? 3) does Private Nick Hooper work at the War Office?
IMDb has a search option for character names.Using it I found:
1) There are 47 entries for Mr Grant and I didn't feel like going through them all,but perhaps something might ring a bell.
2) Lt Frank Ballinger: M Squad (1957) played by Lee Marvin.
3) No Nick Hooper,but there was Pvt Mick Hopper in Dennis Potter's Lipstick On Your Collar played by Ewen McGregor.
