The film by DC Entertainment and Warner Bros., which like CNN, is owned by Time Warner(TWX), also opens in 65 markets around the world on Friday including the world's second biggest market, China. This roll out has led analysts to predict a global opening that could gross over $300 million this weekend.

请问：（1）which like之间为什么没有is？（2）roll out是名词吗？在句中做什么成分？

（1）which like之间为什么没有is？

【答】红色部分是主谓语：

（2）roll out是名词吗？在句中做什么成分？

【答】rollout 是名词，作主语，应为一个单词，意为“首映”。
