The Genre:
* Action: Seagal is known for his action roles, but Alba has mostly played more comedic or dramatic roles. This could be a clash of styles unless the action is balanced with humor or drama.
* Comedy: Seagal's humor tends towards self-deprecation, while Alba is known for her comedic timing. This could potentially work if the script was well-written.
* Drama: Both actors have done dramatic work, but their styles are quite different. It would take a specific story and director to make this work.
The Story:
* The plot needs to be compelling enough to justify their casting. The story needs to be strong enough to carry both actors and their individual styles.
* The roles need to be written specifically for them. Casting them just because they are well-known wouldn't guarantee a successful film.
The Chemistry:
* Seagal and Alba have very different on-screen personas. Their chemistry would be a major factor in determining the success of the film. It's hard to say whether they would be convincing as a couple or even just as co-stars.
Ultimately, whether or not they would be good in a movie together is a matter of opinion. There are plenty of actors who have worked together successfully despite seeming like an odd pairing. The most important factor is a strong script and director who can bring out the best in both actors.
