Two huge blockbuster films are expected to rake in major cash at the box office this weekend. Greta Gerwig's "Barbie" is projected to make between 95 and 110 million-dollars in its debut. Some experts believe the film based on the popular toy will make as much as 140-million-dollars. Meanwhile, Christopher Nolan's "Oppenheimer" is expected to make 50-million-dollars in its first weekend. The two new films plus the second weekend of "Mission: Impossible - Dead Reckoning Part One" are expected to give the box office one of its best weekends in a long time. Thousands of people have actually bought tickets to the starkly different “Barbie” and Oppenheimer,” making the “Barbieheimer” mashup a hot trend.
