I worked for a big agency in London as a scout for about 14 months, before I went to live in foreign parts. My experience was that no matter how good looking a guy was, and no matter what clients were looking for ( edgy and weird, high fashion, corporate and commercial whatever ) height was a big deal. Anything under 6 foot was a hard sell for the agents, and only very few of the guys above 5.10 but under 6 ever got work. I'd send guys along to the agents, who were amazing looking, great bodies, or really unusual and striking and if they weren't 6foot or higher almost all never got any real modelling work. Most just got extras work on TV or in film, so the advice was that if they didn't have some already they should get some more strings to their bow. Acting lessons, journalism qualifications, stage combat, acrobatics, Snowboarding, Lion taming, dance qualifications whatever, because agents get a lot of calls looking for good looking guys with specific or weird talents and a lot of their normal models are just nice to look at and those jobs went a begging.
The guys who did have talents went on to do a lot of TV work, presenting, dramas, acting in general some went on to do TV adverts and stuff like that.
