I think it will be open ended. It’s better to be able to continue the adventures of young Solo.
How old was Han Solo in ANH?
29/30
Yep, although in general Star Wars is vague with character ages and timeframes. I actually don’t even know where this number comes from but it seems to be generally agreed upon.
Only Luke and Leia have definite ages, they were 19 in Star Wars. I wonder if they might age Han to 33/34 (Harrison’s actual age) to allow a bigger gap between Solo and Star Wars.
