Why wasn't Tom Selleck more successful in the movies?

Of course, Selleck had a huge hit while Magnum P.I. was still on the air with Three Men and a Baby (which many people may forget was the biggest box office hit of 1987) but it seemed like his film career never reached further than were it could've gone after Magnum P.I. went of the air.

Had Selleck had done Raiders of the Lost Ark, how would've overall affected Selleck's film career? Or would he inevitably still been stuck to doing mostly mediocre movies that could be filmed in 30-60 days while his TV show was on a break? At that end, was he more or less, a victim of bad timing? For example, the western (a genre that Tom Selleck was theoretically best at) had come and gone by the time he came along.

Was Tom Selleck's problem at the end of the day, was that he never quite got the right role? Or like his Three Men and a Baby co-star, Steve Guttenberg, Selleck had a likable, appealing presence but not much of an edge to his onscreen personality?

His cable western movies had big ratings.

Timing. A lot of the cheap movies were filmed in Vancouver. I saw a scene of his movie Runaway being shot on the streets of Vancouver. It was the era of cheap movies.
