This is a comedy called NO.1.为什么这句话既有“is”又有"called "

called NO.1这个结构叫做过去分词短语,在句子中充当定语“叫做第一的”
相当于which is called NO.1.
这是一部叫做第一的喜剧."which is called NO. 1."这句用的是被动语态吗？是呀。这句定语从句的谓语是is called就是被动语态。
过去分词也是表示被动的（当然，它不是谓语的）
又如：
The boy named Charlie is my brother.
=The boy who is named Charlie is my brother.（叫做Charlie的男孩是我兄弟）The boy named Charlie is my brother.named在这里作定语吗？The boy who is named Charlie is my brother中的is named 是被动语态？
