Would You Pay $400 Million for This Movie?
Between delays, reshoots and rising costs, this year's summer blockbusters are racking up astronomically high price tags when factoring in marketing costs. Can the box office keep up?

Determining unit groups and $\mathrm{K}_1$ of finite rings
We consider the computational problem of determining the unit group of a finite ring, by which we mean the computation of a finite presentation together with an algorithm to express units as words in the generators. We show that the problem is equivalent to the number theoretic problems of factoring integers and solving discrete logarithms in finite fields. A similar equivalence is shown for the problem of determining the abelianization of the unit group or the first $K$-group of finite rings.
