Although he was not as famous as Shana, in terms of development potential, Howard was stronger than she was.
Shana was stuck with an idol image now. Whether she could break out of this image at a later time still depended on herself.
Her looks were sweet and nice to begin with. It would be a little hard for her to break out of that image.
Not to mention how Hollywood was a place that favored males over females. Male actors tended to have a smoother development than female actors and were paid higher as well.
To top it all off, Howard had the backing of Bourbotte.
Although Attack Force had failed miserably here, its ratings overseas were pretty good and Bourbotte's reputation and status were not affected at all.
He was still a god-level director.
As long as Bourbotte was around, Howard would not need to worry about his future development.
