Hollywood actor Amanda Seyfried, known for projects such as "Mamma Mia!" and "Mean Girls", says making sequels back to back is not very brave of the makers.

When sequels have become a trend with more and more projects having a follow-up, the actor feels it is done only for money, and it is frustrating.

Seyfried said she wants to have original content, admitting it is "really scary and brave" to make.
