Star, initially cross with role, rejected stage features (9)

'stage features' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'star initially cross with role rejected' is the wordplay.
'initially' indicates taking the first letters.
'cross' becomes 'rood' (term for a crucifix).
'with' means one lot of letters go next to another.
'role' becomes 'part' (eg a part or role in a film).
'rejected' shows that the letters should be reversed in order.
The initial letter of 'star' is 's'.
's'+'rood'+'part'='sroodpart'
'sroodpart' backwards is 'TRAPDOORS'.

Can you help me to learn more?
