I don't know if Television X actually produce films themselves, but I would imagine if they did they would be far more professional in their approach than this, and it's pretty clear that this is just another timewaster. Did he actually try to get you to make any concrete arrangements in terms of locations, dates, fees and so on?
If a warning is going to be of any use to other ladies, you really need to provide a bit more information - read the 'How to post a warning' thread above - any contact numbers should have the last two digits replaced with asterisks like this '01234 5678**'. Did he ask you anything about yourself or tell you the specific reason he was calling?
If you've only recently started advertising your phone number you need to be prepared for a lot of these calls from guys who think you're green and will tell you anything to try and take advantage - you will also more than likely hear from the Daily Sport, Touch Local, a few random directories (who seem to realise now that we just delete their emails and have started cold calling) as well as the constant and persistant TWs, many of whom are mentioned on this forum and have spoken to a number of us at one time or another. You'll get used to it, and they will fizzle out to maybe one a week or less (I hardly get any nowadays), but if you post a warning every time one calls, you will soon find yourself with no free time whatsoever!
If you didn't read that link I posted on the other thread,
here it is again.
